Theres no way Google won't win the AI race $INTC and $GOOG are good buys right now!
Winning the AI race means obsoleting their current profitable business. They might win but at what cost?
Seriously though, I'm not sure why Google evolving in this manner precludes them from having a profitable business model. Right now we're subsidizing the costs (probably just a bit) and having ongoing subscription revenue they can increase as needed (particularly in the "google won the race" scenario) will be key before they even have to consider layering advertising on top.
