Google seems to be actively attempting to avoid the trap that Apple, Microsoft, Facebook, etc have fallen into. When you completely dominate a market, it can be tempting to optimize and be the best at serving that market. But the nature of tech is such that markets have a short lifespan. New innovations are constantly overturning old monopolies--just ask Microsoft. By investing heavily in high-risk, high-reward prospects, Google is insulating itself against future disruption.

If the display ad market collapsed 5 years from now, Google's investment in AI, self-driving cars, AR, robotics, etc. might be the difference between continued dominance and irrelevance. Tech companies rest on their laurels at their own peril.
