Most people are not creative. Its true. There isn't some horde of people who want to program but don't know it yet because they own a tablet instead of a computer. There isn't some horde of musicians that will never know it because their music comes from an mp3 instead of their own instrument. There isn't some horde of artists who will never know it because their images come from a camera instead of owning a paintbrush. Heck even on a web-forum where contributing content is as low friction as sharing links, only ~10% of users do it. And only 10% of that 10% actually make the content that's posted. 90% of people are happy to passively consume content.
I wish the author were right. I wish there was this huge hidden demand for a real computer revolution. I still think that when I buy a device I should actually own it (which entails freedom to modify). But let's face it idealistic nerd types. We lost. Most people are consumers not creators. Get over it, go to work, program for them, and wipe away your tears with a stack of money.
