Perpetual motion machines are one of the mothers of all snake oil.
Maybe AI can turn base metals into gold too.
Do these AIs even really have a demonstrable understanding of thermodynamics yet?
It needs to prove itself with a usable output for a clear observabe application on a small scale scale before anyone should start chucking vast amounts of energy at it in hope of what it can "maybe" do.
I'd much rather chuck all that energy into trials of tokamaks or something like that.
