Chapter 6 of The Psychology of Money is called Tails, You Win. Just happen to be reading it. The summary is a variant of "lots of small bets" - some will fail, some will do OK, but it's the very few that do exceptional that will matter to your overall success. Google is no special snowflake in this regard, but they hit it big early, and they still have the resources to keep trying things (and hoping for another big win). Lots of consumer-facing useful things that sometimes get popular, but rarely give Google whatever is it they want. And unless it really matters to their bottom line, they probably aren't going to stand behind it long-term. That being said, it's more than fair as a consumer not to trust their (little) bets.
