If a problem is worth the Jeff/Andy's personal attention, it's worth spending $8bn on.
I'm a broken record but, current equity prices and financial climate generally makes massive consolidation very likely. Antitrust, or fear of is the only restraint... and it is not very restraining.
Unless Apple & Google are going to start issuing dividends/buybacks on an epic scale (doesn't seem likely), they have no way to put cash they have to work (besides vanguard/bitcoin). Google would need to do 10 Waymos (in for about $20bn so far) simultaneously, to invest what they need to invest on internal projects, but even their one Waymo is dubious. Acquisition is the only remaining option.
Consider that these companies can currently afford to buy whole industries outright, perhaps without involving a bank. Does Waymo need a friend? Why not buy it Ford & GM? Anything outside the S&P 10 is a snack. They literally have cash enough for both lying around... and these deals are never all cash.
5 more years on the current trajectory, and the VOC/EIC days will look quaint.
