Jonathan Edwards takes quite a stance on open source and what it contributes
Open source and Unix and the internet boom are all wrapped up together. They took over around the same time, 1996, and I blame them for the lack of much progress since.
TL;DR: open source may result in a stagnation, optimizing for stuff nerdy people want to make, and not addressing societies needs.
Which might be true, on the other hand, much of what I have been building is based on open source technology. But what while I have created some open source, most of my work is not open.
