It depends on how you look at it. Thanks to Wikipedia (this was back in 2002-2006) I was able to bypass the problem that half of my university lecturers were researchers first, and teachers a distant second.

Key computer science concepts went from being incomprehensible to being remarkably easy, and I didn't need to spend a small fortune on textbooks either. So to some extent, a revolution has already happened.

I remember a huge controversy while I was in college over whether it was even possible to get reliable information off wikipedia. At the time, my primary use for wikipedia was math articles, so I found this somewhat amusing. The math articles were fine.
