Nobody wants to say it, but Google is basically internet government at this point, and when government starts building products instead of just directing traffic, it's going to be anti-competitive and destroy opportunity in general.
How do they get out of the way and benefit while enabling growth? Move everything new into Ventures and whatever products survive on their own should be taken public in the markets and vertically dis-integrated from advertising and search. If they want to create growth, they're going to need to open it up to public markets, otherwise, they're going to be an anti-competitive monolith.
It's not a charity, and it will still make bazillions, but leveraging their incumbency means they are both risk averse themselves and opportunity destroying for everyone else.
