I don't know if I agree with this, for me the past several years of indie software development have been marked by depression, alcoholism, loneliness, and heart-break. I released an iPhone video game back in 2010, took two years to make, 1000 graphic files I drew by hand, and 20,000 lines of code. And it fell flat on its face; how can someone NOT get depressed when this happens to them? There are probably thousands of indie developers who never make a profit -- is this article referring to developers with "normal" jobs or indie devs?
