I wonder if AI will leave much progress behind when it implodes.
I think it will, it's the one bit of AI optimism I actually have. I have a theory the big AI firms love for example Yudkowsky's doomsday cult so much because it's easier for them to imagine the end of humanity than it is to imagine them not getting an extractive oligopoly over an emerging technology.
The tech itself is actually decent as tech, it's not what the boosters claim it is but even if development stopped advancing today there's loads of niches it'd be changing for a long time; computer vision in medical settings for example. Useful things like TTS will be much better going forward than they ever were, and for better and worse things like computer vision in general (ie in public) will never be the same. LLMs are basically magic NLP boxes too, they're useful for classification as much as generating slop.
