The joy of the demoscene is inextricable from the human and physical nature of it.

Yes, you can have AI tools vibe code up "new" 68k assembly for old machines, but you're never going to see it find genuinely new techniques for pushing the limits of the hardware until you give it access to actual hardware. The demoscene pushes the limits so hard that emulators have to be updated after demos are published. That makes it prohibitively expensive and difficult to employ AI to do this work in the manner you describe.

Don't mistake productivity for progress. There is joy in solving hard problems yourself, especially when you're the one who chose the limitations... And remember to sit back and enjoy yourself once in a while.

Speaking of, here's a demo you can sit back and enjoy: https://youtu.be/3aJzSySfCZM

Re: AI. I believe this will still be a human operation, as far as I can see.

Awesome demo! It's a little bit of middle age crisis :), but superbly done! Thank you.
