It should surprise no one that quantum software companies that *do not build hardware* will flop. It does not matter if it founded by famous Harvard scientists.

Zapata's PR stunts like "Quantum AI" race cars looks all the more comedically delusional now. Though I'm sure no one's learned a lesson from this. No I am not joking, I wish I could make something like this up:
