Instead what they usually do is lower the fidelity and think they've done what you said. Which results in them getting eaten. Once eaten, they can't learn from mistakes no mo. Their problem.

Because if we don't mix up "intelligence" the phenomenon of increasingly complex self-organization in living systems, with "intelligence" our experience of being able to mentally model complex phenomena in order to interact with them, then it becomes easy to see how the search speed you talk of is already growing exponentially.

In fact, that's all it does. Culture goes faster than genetic selection. Printing goes faster than writing. Democracy is faster than theocracy. Radio is faster than post. A computer is faster than a brain. LLMs are faster than trained monkeys and complain less. All across the planet, systems bootstrap themselves into more advanced systems as soon as I look at 'em, and I presume even when I don't.

OTOH, all the metaphysics stuff about "sentience" and "sapience" that people who can't tell one from the other love to talk past each other about - all that only comes into view if one were to what's happening with the search space if the search speed is increasing at a forever increasing rate.

Such as, whether the search space is finite, whether it's mutable, in what order to search, is it ethical to operate from quantized representations of it, funky sketchy scary stuff the lot of it. One's underlying assumptions about this process determine much of one's outlook on life as well as complex socially organized activities. One usually receives those through acculturation and may be unaware of what they say exactly.
