Now, the house is on fire. Have you seen what happens to houses after the firetruck comes & the hose gets turned on? No, it's not pretty. But it's better than letting the fire burn unchecked. And it's too late for mere cups of water to make a difference. So turn on the hose, and accept the costs.

This is why Congress should pass a law giving every sitting member automatic standing if they think a law is not being enforced; they are harmed because their will is not being done by the executive. I would extend that to any former member who voted affirmatively for that law.

This is why AGI isnt happening. Sense perception, movement, and memory are chemistries coupled to each other and all coupled to direct matter exchange with the environment, like a centrifugal governor. Nothing is representation, interpretation, “info processing”, or math.
There is another, radically different way to solve this problem, that is to couple the opening of the valve to something that necessarily varies in response to steam pressure and workload in a way that results in constant flywheel speed. By ‘necessarily’ I mean that the physical properties of this thing respond to changes in steam pressure and workload in a particular way. Such a solution responds in one step and does not require measurement. Thus, there is no time lag problem or concomitant source of error. Nor does it require an executive. In our current example, the thing that responds to both steam pressure and workload is the speed of the engine itself. Hitching the valve control to the flywheel couples the thing you want to control (the valve opening) directly to the thing that embodies the relevant sources of variance (the flywheel speed). So far, so good. The remaining problem is connecting these objects with the proper relation. In this case, we want a negative relation between flywheel speed and valve opening - increased flywheel speed should close the valve, while decreased speed should open it. The solution is to attach weighted arms to flywheel-driven spindle and to link the valve control to these arms (see pic). As the spindle turns, the arms raise and lower according to the centrifugal force generated by the speed of rotation. Faster spinning raises the arms, which pulls the valve closed. Slower spinning lowers the arms, which allows the valve to open. The degree of valve opening / closing varies continuously in response to the height of the arms. The result is uniform flywheel speed linked to oscillating pistons. This beautiful solution is implemented in the Watts centrifugal governor, and 18th century piece of technology that still works brilliantly.Diagram of bacterial chemotaxis. The stimulus ligand is environmental material. The MCP is a sensory receptor that interacts/bonds with environmental material, which triggers a change in rotation of the motor and thus changes the movement behavior of the cell. The “adaptation” mechanism on the left is the memory, it modifies the sense receptor to make it less responsive over time so that it will more likely stay in the area with all the good material instead of flying right through it. All these systems have feedback mechanisms to reset the processes. All things coupled together in  an intricate dance of molecular activity, directly doing things and not measuring, interpreting, or representing.

Let me just explain the arithmetic thing real quick; I'm seeing a lot of people not understanding what it's supposed to show (or was supposed to show in 2023). First, let's agree that an LLM is a Stochastic Parrot, a description which I find poetic, useful, informative, and basically correct.

It may not be so surprising that huge models, specifically of language generated by humans for purposes most often related to navigating, manipulating, or discussing the real world, would derive from that source a statistical proclivity to be applicable to real-world tasks.

Heliocentric @heliocentric.bsky.social · 28/09/2026
Equally worth considering, I think, is how much of the language generated by humans, and thus included in training corpora, is downstream of human encoding of perceptual reality into conceptual forms and symbolic representations.

At the end of the day I don't think most people actually disagree that metaphors can be more or less useful in principle. But it's not fully abstract given we have a whole industry and associated community that uses metaphors to dive right off the cliff.

But like… the thing about statistical models is if the Bad Command is in their ensemble, then eventually the statistical model generates that command with P→1 as T→∞. Which means the person who generated the bioweapon, launched the nuke, or hacked RubyGems is whoever wired the dice roll to the gun.

It's important to remember that if a human *voluntarily attaches* a statistical text generation AI, to a command prompt that can create biomolecules or launch nukes, and a disaster happens, it wasn't because of "intelligence" or malice. It was because statistical models are *fundamentally random*.

Except there’s a big cohort you’re ignoring with this false dichotomy, which is trying to articulate that the anthropomorphization gets in the way of addressing potential harms. If you think it’s “thinking”, instead of acting like software, you pursue an entirely different set of remediations.

But if the buffer is volatile, too, does that distinction matter for this? The audio is still staying in RAM for the duration of the conversion from one stream to another, it’ll just be for an even shorter amount of time. But I don’t think that sounds like a qualitative difference.

How is this different from a regular phone call, though? Audio is captured from the cellular radio and, say, stuffed into Bluetooth packets to send to your AirPods. It’s written to RAM along the way, but would anyone say that taking a call is therefore equivalent to recording it?
