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.
I feel like that argument could be made for some things, but inherently cannot apply to companies involved in personal, genetic, or financial information.
