Yes, I definitely agree that it is possible that an AI could emerge/be built without any direct biological analog, and flight is a good example (and the wheel is another — enables us to go faster than any legged creature but no biological analog).
The questions are whether this generation of AI is actually intelligent (seems we ~agree different degrees of "Not yet"), and whether will lead to real intelligence and how close that is.
Some of this is likely how we define "intelligence". I'm thinking of it in the human+/- level AGI, with the ability to abstract thoughts, sort facts from fiction, reason, and reason about itself sufficiently to set goals. Under this, I consider chess computers, AlphaGo, Watson, current "self-driving" and indeed ChatGPT4 to not meet the criteria, although they do produce very useful output. What's your assessment of these?
Now, how far away are we?
Let's take the arithmetic problem I cited above. I'd bet the OpenAI team is weeks-months away from solving that by generally recognizing all math problems, abstracting them, and passing it off to the Wolfram solve plug-In (like an old subroutine). And that is a level of abstraction that would massively increase usefulness. But, how many of those abstractions must be solved before it can abstract thoughts, sort facts from fiction, reason, and reason about itself sufficiently to set goals?
The generative image systems' problems may be instructive. When asked to show something with a banana, they always show bunches of bananas. This could probably be patch-fixed in weeks with more training to distinguish single/plural bananas. But, I've also seen a "woman on a boat" generating what looks at first like an attractive bikini-clad woman, until we notice that her head & torso are attached the wrong way on the buttocks. This tells us that truly overcoming these problems requires the model to have abstract concepts of all physical objects in the lexicon and understand their relationships, so we don't get legs in impossible tangles or on backwards, etc. That would seem to require an entirely different generation of AI?
I agree that it does not need to be biomicry to be intelligent; that only provides possibly useful hints to useful paths forward.
I also agree that the likely time frame is years-to-decades, not months nor centuries.
>>engineering methods that are dumb relative to how biology sculpts intelligence, and yet still create an AI that outperforms all humans on all intelligence tasks.
Yes, this is definitely possible, especially with scaling. But do you see a path for LLMs alone to get us here with massive scaling up? I'm thinking it needs Large Abstraction Models layered on top of the LLM, sort of like the cortex is layered over and modifies the limbic system, which is layered over the brainstem, etc...?
