Agreed. It's obvious this is written by some pseudo intellectual who wants to feel smart and different by saying they don't use an IDE. Benefits easily out weigh any downsides.
Maybe he was missing a couple things, but it's not far off. Go to college for a major that has high economic value. Continue building your skills after college. Live below your means. I'd like to see data on people who do all of those things and how they end up.
