It could be sci-fi levels of functional, and we still wouldn’t know what to do with it. All we know is that it can do stuff that’d take forever on mere Turing machines. Mostly to fuck up existing encryption. Other magic tricks are as yet undiscovered.

It won’t form a hype bubble, because there’s not even some weird niche use that a cult of MBAs can insist they need, five minutes after hearing about it. Quantum programming is all hideous math proofs.

And should some proof let us say P=NP, our hype will not be a bubble.
