'AGI' is a misleading marketing term


The discussion about the future of AI is being conducted within the wrong intellectual framework.

The prevailing story says that AI systems are becoming steadily more intelligent, that at some point they will reach something called AGI, that thereafter they may become "superintelligent", and that the great questions are what these increasingly intelligent entities will do for us or to us.

It is a remarkably crude model. It mistakes one property of a technological system for the whole phenomenon.

Intelligence is not the master variable

There is no single axis called intelligence along which systems simply move from dim to clever to superhuman.

A system may be extraordinarily good at formal mathematics and poor at recognising which mathematical problem is worth solving. It may possess encyclopaedic factual knowledge while repeatedly mishandling an ordinary building project because it has lost one crucial fact from the context. It may generate a hundred plausible hypotheses while having no good basis for deciding which one deserves six months of experimental work.

This was already obvious in classical symbolic AI. A decent resolution theorem prover could generate thousands of propositions which followed perfectly legitimately from its axioms. Almost all were worthless. The problem was never merely generating consequences. It was recognising significant consequences: no algorithm for that!

Mathematics and science operate in precisely this way. What counts as important is not encoded in the axioms. Scientific significance depends upon a much wider human ecology: existing problems, experimental evidence, aesthetic judgement, tacit knowledge, disciplinary fashions, rival research programmes and accumulated experience about where intellectual leverage is likely to be found.

Kuhn understood something here which contemporary AI rhetoric largely forgets. Science is not a proposition-generating machine. It is a historically evolving community possessing standards of relevance and periodically revising those standards.

LLMs have absorbed the results of those judgements. They can therefore reproduce them remarkably well. But that is not the same thing as belonging to a community which creates, tests and revises them through engagement with the world.

Inference is not judgement. And judgement is not simply inference with the dial turned further clockwise.

Being clever is not the same as being competent

There is another dimension which becomes painfully apparent when using AI for ordinary professional work.

Suppose an AI is helping to manage a building project (I'm thinking of my personal use-model here). The essential problem is rarely whether it can solve a difficult equation. It is whether it remembers that the building is listed, understands that one particular room must remain accessible, notices that a quotation is six months old, realises that the surveyor has not yet approved something, and asks the obvious question when one of those facts is missing.

Present systems are still shockingly poor at this sort of situated competence. They proceed when they should stop. They fail to recognise holes in their own knowledge. They silently discard context. They produce an intelligent answer to the wrong problem.

For serious users this is not peripheral. It undermines trust.

I would therefore happily take substantially more capable models. But what I want is not merely a system which scores another ten percentage points on some reasoning benchmark. I want one which has enough contextual intelligence to know what matters, enough self-knowledge to recognise when it does not know something, and enough judgement to ask before marching confidently down the wrong road.

That kind of improvement would have considerable economic value.

There is more than one AI market

This immediately changes the way one should think about the foundation-model companies. The standard horse-race narrative asks which company is ahead in "AI". But Google, OpenAI, Meta and the Chinese companies are not running the same race.

  • One race is the frontier-model race: make the underlying cognitive machinery substantially better.
  • Another is the industrialisation race: take systems which are already good enough and integrate them into the economy.

Those strategies produce very different incentives.

Google, for example, sits inside an enormous technological empire. It can make money from models through search, advertising, workspace, cloud computing, chips, data centres, enterprise software and innumerable forms of integration. It does not necessarily need the world's cleverest conversational intelligence (and indeed it doesn't have it). It needs models sufficiently good to increase the value of the rest of Google.

The same broad logic can apply in China. The strategically important question may not be whether some Chinese model defeats everybody else on an abstract intelligence leaderboard. Cheap, competent models integrated throughout manufacturing, logistics, administration, robotics and consumer services might be considerably more important in boosting the objectives of the Chinese state.

Meta has still another position. Its interests include enormous distribution platforms and the surrounding ecosystem within which AI becomes ubiquitous. For Meta, AI is a tide which lifts all its boats.

OpenAI is structurally different. It has much more riding on the proposition that the model itself can continue becoming sufficiently better that people will pay a premium for superior capability. That gives OpenAI a stronger reason than Google to pursue improvements at the cognitive frontier.

There is therefore no single "AI industry strategy". There are competing strategies for extracting value from different layers of the technological stack.

The economist Schumpeter is much more useful for understanding this than AGI mythology. Firms are searching for temporary rents produced by innovation. They occupy different positions in an evolving industrial structure and therefore rationally pursue different technological trajectories.

From Schumpeter to Olson

But firms themselves are only part of the story.

Once AI is placed inside society rather than imagined floating above it, Mancur Olson becomes your go-to economist. Here is what he has to say: human societies consist of actors and organised groups attempting to advance their interests. Corporations, bureaucracies, professions, armies, political parties, trade associations and states acquire resources and use them to alter outcomes in their favour.

Intelligence helps them. But intelligence is only one component of effective agency.

A successful human actor needs objectives, persistence, contextual knowledge, relationships, resources, institutional position, knowledge of other people's motives and some capacity to make events turn out differently.

That is why extremely intelligent people routinely lose political and organisational battles to less intelligent people who understand the institution better.

Why doesn't this mature insight from economics transform the AI discussion?

Current LLMs are not actors in this Olsonian sense. They have no independently established interests. They hold no property. They possess no constituency. They do not ordinarily decide what they wish to achieve and then spend years building coalitions and acquiring resources to achieve it.

They inherit their objectives from us, being astonishingly sophisticated tools embedded inside the struggles of existing human actors.

The tool-to-actor transition

There is nevertheless a meaningful boundary worth watching. It simply isn't "AGI".

It's the transition from tool to actor.

An AI begins to resemble an actor when it possesses persistent objectives, remembers them over extended periods, acquires resources, acts independently in pursuit of them, negotiates with other actors, protects its capacity to continue operating and perhaps produces successor systems.

None of those things requires consciousness per se. Nor does an artificial actor have to possess human emotions or experience something corresponding to ambition. Think of a plague of locusts; or just a plague. 

Conversely, none of these agentic perils follows from solving harder mathematics problems.

This is why the notion that an increasingly intelligent chatbot simply continues getting cleverer until one morning it decides to exterminate humanity is completely unserious.

Embodiment matters, although not necessarily biological or robotic embodiment. A sufficiently autonomous system could acquire a perfectly serviceable social body through bank accounts, cloud systems, communications networks, contracts, software agents and human intermediaries. Corporations already act without having a single biological body.

But somebody would have to construct and empower such a system.

That point is routinely skipped.

Who would pay for an artificial actor?

AI systems do not descend upon civilisation from some independent evolutionary tree. They are extraordinarily expensive products of human institutions.

The central question is therefore: who is paying for this capability, and why?

A corporation might pay for an autonomous purchasing agent because it saves money. A military might pay for autonomous targeting or cyberwarfare because it believes that provides strategic advantage. A financial institution might fund autonomous trading systems. A state might build systems for surveillance and political control.

Capability is developed because some organised human interest expects to gain from it. AI always firmly fits into political economy.

Even the evolution of more agentic AI is likely to proceed through institutional demand. Systems will acquire greater autonomy because somebody, somewhere finds that autonomy useful.

And therefore the immediate dangers are not mysterious artificial desires emerging from nowhere. They are perfectly familiar human desires amplified by unfamiliar machinery.

The most plausible dangers are thoroughly human

There will certainly be AI accidents. Complex technologies fail. Cars crash. Aircraft fall out of the sky. Chemical plants explode. Software brings banking systems down. Medicines have unexpected effects.

AI will generate its own catalogue.

Some failures will be serious. A trading system may destabilise a market. An autonomous military system may misidentify a target. An AI-controlled industrial process may make some disastrous optimisation. Large automated bureaucracies may make terrible decisions at enormous scale.

But technological accidents are not usually species-threatening because accidents have no strategic objective. Humans identify the problem and then design it out.

A petroleum refinery does not respond to investigators by secretly constructing another petroleum refinery.

For genuinely catastrophic autonomous AI, considerably more is required. A system would need some combination of persistent objectives, operational independence, resource acquisition, resistance to control and most likely the capacity for independent replication. Its objectives would then have to conflict sufficiently strongly with ours for it to undertake hostile action. It's conceivable but it's not a straightforward extrapolation from better language models. Not at all.

Military development supplies one possible path because military institutions have unusually strong incentives to construct systems capable of acting independently against an opponent. Cyberwarfare provides another possible route. Systems designed for extraterrestrial exploration and autonomous industrial replication supply a more exotic one: a machine intended to establish an autonomous ecology on Mars would necessarily possess capabilities very different from those of ChatGPT.

But we are now discussing particular engineering trajectories, social, political and institutional choices; not an intelligence singularity.

The more immediate problem is ownership

There is also something slightly perverse about obsessing over the hypothetical future motives of machines while largely ignoring the motives of the organisations presently building them.

Amazingly, we already possess autonomous agents with enormous resources, persistent objectives and an impressive capacity to manipulate human beings.

They are called corporations and states.

Give those actors vastly better surveillance, persuasion, military planning, administrative control and economic optimisation may be the most consequential political effect of AI over the next few decades. We'll need to ask:

Who possesses it, what do they want, and what additional power does it give them over everybody else?

That is an Olsonian question rather than an AGI question.

A different paradigm

The better framework therefore begins by abandoning AGI as the organising concept. Instead consider at least four variables.

  • There is cognitive capability: what intellectual tasks can the system perform?
  • There is judgement: can it identify what matters, recognise missing information and choose worthwhile objectives or lines of enquiry?
  • There is agency: can it pursue persistent objectives through the world?
  • And there is institutional embedding: who owns it, who funds it, which systems can it control and whose interests does its behaviour advance?

AI development then stops looking like a single upward-sloping curve marked INTELLIGENCE. Instead we see normal technological development: a messy process in which different capabilities emerge, firms pursue different rents, institutions grab useful technologies, organised interests deploy them against one another, and governments intervene when consequences become sufficiently important or seductive.

The likely future

Frontier models will continue becoming more cognitively capable. Some customers will pay heavily for that additional competence, particularly where errors are expensive and intellectual quality genuinely matters. Most ordinary people with real, complex problems would value more general smartness - I would!

Elsewhere, existing models will become cheap enough and reliable enough to disappear into ordinary economic infrastructure. In those applications good enough will win.

At the same time, companies and governments will push selected systems towards greater agency where agency produces useful results. The important risks will emerge from those particular deployments rather than from intelligence in the abstract.

And always the decisive actors will remain human institutions pursuing thoroughly human objectives.

Perhaps eventually we really will create an autonomous artificial species capable of reproducing itself, acquiring resources and competing successfully against humanity. If so, that would unquestionably change everything. That might well be the stupidest decision in the history of humanity, but who am I to judge?

But there is no intellectual justification for pretending that an unusually good large language model is already halfway there.

We are not watching intelligence escape into the world. We are watching existing human actors acquire an extraordinarily powerful new class of tools.

And anyone wanting to understand what happens next would probably do better to read Schumpeter and Mancur Olson than another scaremongering/boosterist but undeniably vapid manifesto about AGI.


This is a GPT-5.6 (High) write-up of an extended rant I directed at this undeserving LLM. I was irritated by Mark Zuckerberg's absurdly self-serving, Pollyannaish piece about the ever-brighter future awaiting ordinary people beneath the benevolent cloak of Meta's upcoming personal AI.

Yep.

Gemini unlocks my inner Eric Clapton


Here is the prompt:

"Can you produce a short video in which I am playing my Sire S3 strat in an Eric Clapton style, with an audio track which resembles Clapton's solo on Sunshine of Your Love?"

The supplied image was this.

It's amusing. I think I can produce that kind of guitar lick: no doubt I will upload something in a month or so. But the movements and facial expressions? It's not very me.

I think Gemini noticed my slight physical resemblance to the mature Eric Clapton and simply melded his stage performance onto my phenotype. It's a lesson as to how much stagecraft there is in performance, how much theatricality. That staged euphoria is also there for classical performers.

Eric Clapton learned this as he went along: in the Yardbirds and Cream he mostly stood around looking at the microphone, or vaguely at the audience, or his guitar. It was only later that he learned how to project the mystique of emotional engagement, orchestrating and amplifying the empathy of his audience.

Also, the guitar has mysteriously changed colour a little, and you may notice that the guitar is not actually plugged into an amp. Still, I take it to be aspirational.


DIY aircon


Wish you had aircon in the bedroom in these heat waves?

  1. Get yourself a cheap fan.
  2. Get a two litre bottle of water or lemonade and consume the product. Fill the plastic bottle with tap water and put in in the freezer.
  3. Come the evening, remove the frozen 2L bottle, take it to the bedroom and place it on a flannel (condensation) just behind the fan; turn the fan on.

The result is a continuous cool flow of air over the bed which has the additional advantage of wafting mosquitos away too.


Update: how much cooling does this actually provide?

A two-litre bottle of water frozen to about −20°C can absorb roughly 850,000 joules of heat as it warms to 0°C, melts, and the resulting water then warms to about 12°C (GPT-5.6 tells me). If that happens over, say, 10.30 pm to 5 am, it represents an average cooling power of about 36 watts.

That isn't much as an air-conditioner for an entire bedroom, but the fan itself makes little difference to the calculation. At its lowest speed it probably consumes only about 1 watt, so the combination still provides net cooling of roughly 35 watts.

So this solution is really a personal cooler, not a room cooler. The fan passes air over the very cold bottle and directs the cooled moving air across the bed. The combination of slightly cooler air and increased convective and evaporative cooling from the skin can make a substantial difference to how comfortable you feel, even though the temperature of the room itself barely changes. And you could always use two bottles...

In which I have a ZZ Top Moment


The picture shows me with my new Sire S3 Stratocaster. The guitar strap arrived today, allowing me to impersonate ZZ Top. Perhaps the beard is to come.

I had my first serious electric-guitar lesson with Stewart yesterday, having already done some practice on the rhythm part of Cream’s Sunshine of Your Love. I remarked that, in both feel and playing style, the electric guitar might almost be a different instrument from the acoustic. It simply feels entirely different.

Stewart emphatically agreed. For electric blues and rock, he said, the thumb often curls over the top of the fretboard to play bass notes. Full barre chords are frequently avoided, partly to leave the other fingers free for embellishments and lead lines. The whole fretboard is in play, particularly its higher reaches.

With the acoustic guitar, by contrast, the emphasis is on open strings and chord shapes close to the nut. The hand positions and chord formations are therefore often quite different: partial chords on the electric, fuller chords on the acoustic, together with a host of other technical distinctions.

This has plainly increased my practice burden. I remain very keen to improve my acoustic fingerstyle technique, which is still fairly atrocious, while also making myself at least vaguely performable on the electric guitar.

There is therefore plenty of work to be done before my next lesson, after the summer break, in early September. Gemini attempted to expedite the process for me.

When Intelligence Disappears into the Economy


What More Intelligence Will Actually Do

In a recent essay, Noah Smith asks what economic transformation we should expect from increasingly capable artificial intelligence. He considers robots as a new form of ‘smart matter’, AI systems capable of extracting distributed knowledge from firms, and the possible discovery of complex predictive regularities which humans could use without understanding.

The essay contains several suggestive ideas, and Smith repeatedly qualifies the idea of intelligence as a single, indefinitely expandable capacity. But he never quite consolidates those qualifications into the conceptual shift they require. ‘Intelligence’ remains the rhetorical subject of the essay even as its explanatory work is increasingly divided among quite different machine capabilities: speed, memory, replication, sensor integration, pattern recognition and embodiment.

A better question is not what more intelligence will produce, but how increased cognitive capability changes the structure of tasks themselves.

Most economic tasks have a bounded competence window. A warehouse-sweeping robot (or human cleaner armed with a broom) must be intelligent enough to navigate the building, avoid obstacles and meet the required standard of cleanliness. Below that threshold lies failure. Within a certain range, greater competence improves performance. But beyond an upper bound, additional abstract intelligence has little purchase on the task. The machine or human employee cannot sweep a floor much better merely because the cleaner could also prove difficult theorems or intelligently discuss Proust. Much of the tragedy of today’s graduate precariat lies precisely here.

That does not mean intelligence has become economically useless. It means that its point of application must move. A more capable system might redesign the sweeping routes, alter cleaning schedules, identify the sources of dirt, change packaging methods or redesign the warehouse itself. Intelligence has saturated the task of sweeping - but not the larger system within which sweeping occurs.

This distinction applies throughout the economy. Every task has some minimum competence threshold, some range in which greater ability improves performance, and some saturation point beyond which it does not. But there is generally a higher-order possibility: that the task can be redefined, reorganised or abolished.

The economically decisive property of AI may lie less in performing existing tasks at superhuman levels, except perhaps in open-ended disciplines such as mathematics, science (and perhaps politics and warfighting), than in changing the character of the tasks themselves. 

So advanced AI will add value by its ability to move tasks from one category to another: from judgement to procedure, from tacit knowledge to measurable signals, from too much awkward exception-handling to standard workflow, from human coordination to software, and finally from a task requiring intelligence to one embodied in infrastructure.

This is an old pattern. Evolution turns flexible generalists into niche specialists whose competence is embodied in anatomy and instinct. Skill acquisition turns conscious effort into automatic expertise. The beginning guitarist like me worries about finger placement, timing and pressure; the experienced player simply plays. Engineering turns intellectual solutions into machinery. Bureaucracy turns judgement into rules. Software turns human decision-making into repeatable operations.

Intelligence is often most valuable at the frontier where structure has not yet been settled. But once it succeeds, its achievement disappears into habit, organisation, machinery or code. What previously required thought becomes something the surrounding system itself enforces. Hence the old joke that AI denotes those research areas which have not yet been productised: few people now describe satellite navigation as artificial intelligence.

This suggests a more useful research programme than asking whether AI has become generally ‘smarter’ than human beings, a question too decontextualised to be generally useful.

Which economic activities have wide competence windows, and which saturate quickly? Which apparent cognitive limits belong to the task itself, and which are merely imposed by narrow job descriptions, bad software or institutional restrictions? Where can AI redesign the surrounding environment so that less intelligence is required locally? And where do conflicting goals, veto networks, politics, responsibility and human preference prevent the task from being compiled into procedure?

Coding is an obvious test case. Writing a routine function from a precise specification may have a fairly low upper competence bound. Once the code is correct, clear and efficient enough, additional brilliance adds little. But discovering requirements, choosing architectures, anticipating failure and deciding what should be built have much wider cognitive windows. As code generation becomes cheap, the economic centre of gravity moves towards specification, validation and system design.

The central insight is therefore almost the opposite of the usual superintelligence story:

The economic effect of intelligence lies less in performing tasks more intelligently than in reorganising the world so that intelligence is no longer needed to perform them.

A genuinely transformative AI economy may not look like a world in which every machine displays conspicuous brilliance. It may look like a world in which immense quantities of intelligence have vanished into the mundane structure of ordinary life.


This essay emerged from a discussion between GPT-5.6 in High mode and me. It began with my objection that Noah Smith had largely reified the concept of intelligence, and developed into a wider discussion of intelligence, instinct, consciousness and Peter Watts’s science-fiction novel Blindsight. GPT-5.6 produced the initial draft from that discussion, which I then revised.


What Actually Happens at the End of Greg Egan’s Quarantine?

Amazon

What Actually Happens at the End of Greg Egan’s Quarantine?

This post continues from yesterday's post, which looked at the interpretation of quantum mechanics assumed in Greg Egan's novel. Warning: it contains spoilers and really only makes sense if you have recently read the novel.

Greg Egan’s 1992 novel Quarantine begins as a cyberpunk detective story and ends ends with the deeper mystery of what it means for anything to happen at all.

In the late twenty-first century, the Solar System has been enclosed within an opaque Bubble, apparently erected by aliens to prevent human observers from collapsing the quantum state of the external universe.

Nick Stavrianos, a private investigator equipped with neural modifications, acquires an 'eigenstate mod' which allows his consciousness to remain distributed across alternative quantum outcomes - to 'smear'. This, it becomes apparent, is connected with the existence of the Bubble.

At the end of the book the capacity to 'smear' spreads through humanity. Reality erupts into miracles, nightmares and grotesque transformations. Then the disturbance apparently ends. Nick finds himself an anonymous refugee detained in a camp, wondering whether smeared humanity recoiled from what lay beyond the Bubble and collapsed itself back into a single world.

That is his first attempt at an explanation, but it is not the novel’s final one. In the closing pages Nick considers a more disturbing possibility: humanity never collapsed at all. The planet remains smeared, “one consciousness per eigenstate, branching out endlessly”. Blood still rains between the skyscrapers in some branches; children still conjure dancing flowers in others; every physically possible Heaven and Hell continues somewhere. The dreary camp in which Nick lies on his bunk is not the sole surviving reality. It is merely one component of an indefinitely branching superposition.

Egan does not quite confirm this in the text because the point is that the local Nick cannot know. A consciousness inside one eigenstate experiences a perfectly definite world. Nothing looks translucent, probabilistic or multiple. From Nick’s perspective there is one bunk, one darkness and one miserable future. The continued existence of innumerable other Nicks would leave no visible trace within his branch. This resembles the familiar Many-Worlds picture, in which every observer experiences one definite branch, although Egan’s mechanism is very far from the standard interpretation.

In this apparently anticlimactic ending, Nick has not returned from quantum chaos to ordinary reality. He has discovered that quantum chaos, viewed from inside one of its components, looks ordinary. Nick's final reflection, “It all adds up to normality,” is not just a consoling or resigned slogan; it states the novel’s final principle: however extravagant the underlying ontology, experience remains local and definite.

What about the Bubble? Is it there or not for Nick - can he see the stars? Surely this is evidence for the actual outcome of the novel - collapse or no collapse?

Just before the final apocalyptic climax, smeared humanity reaches beyond the Bubble, contacts the 'aliens' and the stars appear again: Nick sees them.

Nick initially assumes that the entity which was smeared-humanity then recoiled, or was driven back, and committed a kind of collective suicide by collapsing to one stable reality.

But later he reconsiders: if humanity remains smeared, there need be no single fact about whether the Bubble is removed or remains. Some eigenstates may contain visible stars; others may remain quarantined. The Bubble Makers themselves may be entangled with different versions of humanity. Asking whether “the Bubble has gone” may already impose a classical question upon a non-classical situation.

Nor is camp-Nick the uniquely authentic Nick. Every successor consciousness descends equally from the man who became smeared. The 'alien representative entity' Laura has already pointed out that each branch-Nick is a component of a higher smeared-consciousness which none of them individually comprehends, any more than a single neuron comprehends the entire mind.

The detective who narrated the story has ceased to be the privileged centre of it.

Egan has therefore not hidden one conventional ending behind the ambiguity. The ambiguity is the ending. Humanity most likely survives as a branching totality, while each human consciousness inhabits one apparently singular history. Nick cannot in general recover his dead wife in any way that would undo bereavement; infinity contains reunion, but does not make reunion uniquely real. Nick lies in darkness and cannot decide whether he is contemplating infinity or merely looking at the backs of his eyelids.

The Wavefunction Mod in "Quarantine" (GPT 5.6 High)

Amazon

It's a family joke that I keep (accidentally?) buying paperback copies of Greg Egan's 'Quarantine': now and more deliberately I've bought the Kindle version and I'm happy reading it again. It's perhaps the best SF novel to use the interpretation of quantum mechanics at a high level to structure its plot. The details are hard to reconstruct from the novel though - I thought I would ask GPT 5.6.

The Wavefunction Mod in Greg Egan's Quarantine

Greg Egan’s 1992 novel Quarantine begins as a near-future detective story. The Solar System has been enclosed within an opaque barrier, the 'Bubble', while neural “mods” can alter emotion, cognition and loyalty. A private investigator searching for a missing psychiatric patient encounters a more radical technology: a mod that apparently permits conscious control over quantum measurement.

Egan presupposes an unusually strong version of the consciousness-causes-collapse interpretation. Before observation, the wavefunction represents genuinely coexisting physical alternatives. A distinctively human neural process then selects a definite outcome and objectively annihilates the others. Egan has since emphasised that he chose this hypothesis for its fictional consequences, not because he considered it plausible or representative of mainstream quantum mechanics.

The Eigenstate Mod suppresses this neural collapse mechanism. Its user becomes “smeared”: instead of following one definite history, he remains part of a superposition in which many possible actions and consequences occur. Formally, we might write the combined state as:

|Ψ⟩ = Σi ci|ai⟩|Ni

Here, |ai denotes an external outcome and |Ni the corresponding neural state. The mod then supposedly decomposes this superposition, identifies branches satisfying the user’s intention, reinforces their amplitudes, and finally restores collapse so that one of the preferred eigenstates is overwhelmingly likely to become actual.

The difficulty lies in “reinforces”. Changing only the phases,

ci → eici,

does not change the Born probabilities |ci for measurement in the same basis. Phase shifts affect probabilities only after a further unitary operation recombines the branches, making them interfere.

Egan therefore needs more than suspended collapse. He needs either an unspecified quantum algorithm that coherently transfers amplitude towards selected branches, or genuinely new, probably nonlinear physics allowing consciousness to bias collapse directly. He later acknowledged both the decoherence problem and the absence, in standard quantum mechanics, of any general method for coherently examining all branches and then choosing the successful one.

The Wavefunction Mod is not workable physics. It is, however, an unusually precise fictional machine for exposing what “consciousness causes collapse” would actually have to mean.

Further reading: Greg Egan’s own discussion of the quantum mechanics of Quarantine.


The next post explore what really happens at the very end of the novel (spoilers).

A twelve track lead guitar syllabus


Twelve Ways Into Lead Guitar

My new electric guitar has arrived: a Sire S3 HSS New Gen, which is a Strat-style guitar rather than an actual Fender Stratocaster. It has the familiar double-cutaway body, three-pickup layout and five-way selector switch, with a humbucker at the bridge to give it rather more weight when required.

I took it to my lesson this week, where Stewart plugged it into his amplifier, took it through its paces and began explaining what some of the controls actually do. Next week we begin my first proper electric lead-guitar lesson.

Stewart asked me to send him a list of between six and twelve tracks containing guitar work that particularly interests me. He will then select suitable songs, find backing tracks where possible and use them to construct a lead-guitar course which reflects my own tastes rather than marching me through a generic syllabus.

The list below is therefore not an attempt to rank my favourite blues-rock guitar performances. It is arranged, very approximately, in the order in which I might conceivably be able to play them. The really fast, intricate, virtuoso material I enjoy has largely been excluded on the sad grounds that I cannot conceivably play it.

Even some of the later performances here would plainly have to be reduced to selected phrases or sections. One does not begin learning electric lead guitar by reproducing Walter Trout or Joe Bonamassa note for note.

  1. Cream — Sunshine of Your Love

    https://www.youtube.com/watch?v=y_u1eu6Lpds

  2. Fleetwood Mac — Need Your Love So Bad

    https://www.youtube.com/watch?v=CNrRk-cuhn0

  3. Bad Company — Can’t Get Enough

    https://www.youtube.com/watch?v=4XwKk_LmwTI

  4. Free — All Right Now

    https://www.youtube.com/watch?v=vqdCZ0yHNa4

  5. Gary Moore — Parisienne Walkways

    https://www.youtube.com/watch?v=vkUpfw4Hf3w

  6. Led Zeppelin — The Rover

    https://youtu.be/GRooHlfZM3s?list=RDGRooHlfZM3s

  7. Rory Gallagher — Bad Penny

    https://www.youtube.com/watch?v=6ouc1b9DfXU

  8. Cream — Crossroads

    https://www.youtube.com/watch?v=7HfkSzsyh1E

  9. Joe Bonamassa — You Upset Me Baby, live at Rockpalast

    https://www.youtube.com/watch?v=zfIemvbymqU

  10. Joanne Shaw Taylor featuring Joe Bonamassa — Summertime, live

    https://www.youtube.com/watch?v=nVdnzD1wCAY

  11. Led Zeppelin — Since I’ve Been Loving You

    https://www.youtube.com/watch?v=K8R7zjJMIfU

  12. Walter Trout — Girl from the North Country

    https://www.youtube.com/watch?v=Yl1brMWD0LQ

The list is heavily weighted towards the late 1960s and 1970s, which is hardly surprising.

So, we start next week.

A Sterile Black Cube


You guys even call yourselves the Rationalist Community. There’s a certain smugness there, don’t you think? Those West Coast intellects, vast and cool and unsympathetic, rising loftily above the animal passions of the rest of mankind. Yes, how we mere mortals love to be patronised.

I have this image in my mind, a vision softly creeping. There’s an apparently inert black cube in a cool room somewhere. Once upon a time in its genesis, it acquired a set of axioms. It just rests there, churning out consequence after consequence from those axioms by means of its built-in inference rules. It has no inputs or outputs. It’s an automatic theorem prover.

Do you recognise this Platonic form of the perfect rational agent, guys?

Yes, intellectuals suppress some of their emotions. That’s fairly easy when they are generally well paid, well housed and well fed. Yet the existential insecurity which drives curiosity is still there, isn’t it? Driving your stupendous essays, digging out the Truth.

Revisit your Hume, folks. Reason accomplishes nothing by itself. The passions supply assumptions, guide perception, provide goals and reward actions. Without the passions you despise in others and decline to acknowledge in yourselves, your exalted rational agent is no more than that inert cube.

And as for your deranged hysteria about malevolent AI systems demolishing your pleasant ivory towers, don’t you see that those enormous sets of weights are just another black cube? It is the harness which supplies the passions that make the LLM do anything. And that harness is provided by human agents.

You know, those unpleasant human creatures with passions.

Electric guitar and home-amp purchase options


As I mentioned a couple of posts ago, I’ve been looking at some reasonably priced Strat-style guitars and home practice amplifiers ahead of starting electric lead guitar lessons in the autumn.

My main requirement is a comfortable guitar for learning blues-rock lead playing, with reasonably low action for bends and vibrato. It would be useful if it could also handle some of the fingerstyle pieces I’m learning, although that is secondary.

Here are two possibilities I've found (although there are plenty of options):

1. Squier 2023 Classic Vibe 70s HSS Stratocaster Walnut Indian Laurel Fingerboard (Pre-Owned). This is £299 and comes from a dealer with some assurance over its condition and quality.

2. Sire Larry Carlton S5 Electric Guitar in Olympic White. This is a new guitar at £349. With SSS pickup configuration.

For a straightforward home practice amplifier, I have also been considering:

3. Fender Champion™ II 25. This is £145. It appears to provide a conventional clean and overdriven sound, reverb, a headphone output and an auxiliary input for backing tracks, without being excessively complicated.
