LOL, if you look at the amount of money Google has poured into Google and how much they got back for their investment, it's laughable.
Things like the Wavenet "contributions" are just Demis paying lip service to the fact that once in a while Google was nudging them to produce something, anything really that was actually useful.
Google putting the extreme amounts of easy dollars they have into things that aren't instantly profitable is very much what the founders said they'd do though
