How about the more practical question: does it solve any classes of problems faster than an equivalently priced classic computer? What are these problems?

...if they don't come up with answers to this questions that are easy for business persons to understand, then we can only think that they are playing "fake it 'till we make it" on US gov's money. And if, god forbid, they don't make it, we'll be in for a "quantum computing winter(s)" just like we had the "AI winter(s)" because of smart assholes that played a similar game... and boy we have a lot to "thank" them for!
