Because I used to be involved in a tiny bit of it.

Don’t get me wrong, they are a beautiful invention in the intersection of physics and engineering. But the algorithms that people are interested in were executed only on ion computers… which are not that great in the sense of scaling. The supercubit quantum computers, which you are probably talking about, are only good for stimulating themselves for a fraction of a second. And don’t make me start to talk about neutral atoms, NV centers and “liquid light” platforms.

The only good they are making is sucking money for fundamental physics from big cats like google, amazon, putin and ccp
