OOTL: what is this machine in the thumbnails I keep seeing associated with AI?

That's actually what current quantum computers look like. The chips themselves are reasonably small, but the whole metal apparatus you see is there to keep it close to 0° kelvin, as the quantum bits kinda just "dissolve" if they're not in a superconducting state. Not super knowladgable in this area, but that's my layman's understanding.
