Most of the interesting projects on Github were written by professionals and are far better quality than the average "professional" day-job application because it is a developer's passion and not constrained by business development.

I do not believe open source solves all problems, but you dismiss the incredible value and quality of so much that I find it difficult to take the rest of the comment seriously.

It sounds more like "People with credentials (whether scientists or professional programmers) are the only people who can produce quality work. I have credentials. I'm part of the elite who can do quality work."
