Uh oh
This could bring great things, but based on the track record of the companies involved, this will boil down to a quantum computer that really isn't, hyped with a mountain of fluff and weasel words, backed by a marketing campaign to convince punters that there is, in fact, a quantum witch behind the curtain of flashing LEDs. Google will take care of begging, borrowing or stealing the data required to feed the system and exploit victi—, sorry, customers, and VW can handle faking the results to help them sell cars (whether this ultimately kills people or not, so long as it makes money).
And if that sounds cynical, consider Don't Be Evil's history with data, and VW's with a massive fraud designed to help them sell excessively noxious cars that have contributed to pollution deaths across the world.
The fact that quantum computing, right now, is amusingly both there and not there, just adds to the worry that we're about to be victims of another cloudy, AI-type hype-avalanche.
