Earlier quoted context omitted.
I don't think this is true for Google. The "Moonshots" mentioned here are pretty far from Google. It is in some sense R&D of course, but it is not R&D that will benefit Google as a company.
How do you reach the conclusion that it is not R&D that will benefit Alphabet? They make it pretty clear it is a high risk high reward R&D, meaning if they hit pay dirt, it can be massively profitable for Alphabet.
If they pay off, it benefits Alphabet. Maybe Google (the search engine monetized through advertising) but possibly not.
