>I honestly though Google would be that - but apparently it's easier to fund R&D on "selling copying machines" than "selling ads". Maybe "selling ads" earn _too much_ money ? I don't know.

Google has put quite a bit of resources into quantum computing research. It's not just for selling ads, though I have no doubt that it will be used for that among other things. But right now there's still no guarantee it's going to pay off at all.
