I guess you could at least mine the boards from defunct AI companies for memory chips ? Latest videos from Gamers Nexus showed it is apparently not that hard to transfer memory chips from board to board.

Then you can leach precious metals from the PCB itself.

Yes, but if they weren't overproduced and then either run into the ground or left waiting for demand that would never come, then wouldn't those memory chips and precious metals all still be more available than otherwise...?

I mean, sure, yes, we can try to recycle waste products—but it's still less wasteful not to produce them unnecessarily in the first place.
