Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

Can we all take a moment to appreciate this absolutely wild take from Google's latest quantum press release (bolding mine) https://blog.google/technology/research/google-willow-quantum-chip/
The more I think about it the stupider it gets. I'd love if someone with an actual physics background were to comment on it. But my layman take is it reads as nonsense to the point of being irresponsible scientific misinformation whether or not you believe in the many worlds interpretation.
these are some silly numbers. if all this is irreversible computation and if landauer principle holds and there's no excessive trickery or creative accounting involved, then they'd need to dissipate something in range of 4.7E23 J at 1mK, or 112 Tt of TNT equivalent (112 million Mt)
(disclaimer - not a physicist)
How do you figure? It's absolutely possible in principle that a quantum computer can efficiently perform computations which would be extremely expensive to perform on a classical computer.
