I was at a startup, we almost never wrote tests, just hacked like amateurs in the way this guy seems to despite. But we managed to sell the startup and got rich. Now the software we hacked together is being maintained by professional programmers. They have tests and all those fancy processes and what not. They get paid nice salary but they'll probably never get rich like the founder programmers. I'm pretty sure also we wouldn't got rich with writing the unit tests and what not. We just needed to implement it quickly and provide good enough version. To me the writer sounds more like loser than the amateurs he mocks. But I guess it is on whatever side of the fence you are. Nothing wrong preferring one or another.
