For tech, it's all hard problems now

The tech industry spent the last two decades connecting the world and getting computers into every home and hand — but that's turning out to have been the easy part. Now, every problem tech companies face is fiendishly hard. Facebook, Google, Amazon, and Apple have entered a world where their product innovations and profit margins are beginning to matter less than their ability to navigate treacherous political, social, and ethical rapids. Policymakers and engineers are both accustomed to making and living with tradeoffs, but someone has to make a final call over where these choices land. The fight now is over who that will be: companies, governments, or the public.
