My only fear: letting people get controlled by the advertisers and the government, each of whom are power hungry and relentless.
That's the real problem. Today, a computer user with any sophistication spends a great deal of time fighting their device and operating system to make it be the owner's servant rather than a spy and advertising delivery device. Rather than coding apps for my phone, I spent a lot of time this week finding hacks to fake location services for an intrusive app I wanted to use. (Just fake GPS doesn't do it anymore when apps use Google Play services and check your location via networks. The answer, BTW, turned out to be an Xposed module.)
