Have to think of it more like how quantum computers are right now. You aren't going to be running minecraft or a web browser on it, but it'll probably be very good at doing certain things. Those things can either be in their own silo never interacting directly with a traditional computer, or information will be sent between them in some way (such as sending a calculation job, then receiving the answers). That send/receive can afford to be slow if some translation is needed, if the performance gains on the actual task are worth it. It's not like a GPU where you would expect your frames to be rendered in real time to play a game.

Eventually that may change but until then it's no more than that, articles like these put a lot of hype on things that while very interesting can end up misleading people.
