Someone said that Linux was progressing only through sheer luck… And this make Linus Torvalds react:
And don’t EVER make the mistake that you can design something better than what you get from ruthless massively parallel trial-and-error with a feedback cycle. That’s giving your intelligence much too much credit.
Linus was referring to the open source development model (have you read The Cathedral and the Bazaar? You really really should!) compared to the classical corporate model of software development.
And, of course, he is right.
