To invent something totally new and different just because you want to do something new and different is in my opinion, the height of stupidity and hubris.
I totally agree on the evolution side of things. And not to reinvent the wheel where it shouldn't be.
I have to continually try to explain to people that no, I don't "control" what happens in Linux. It's about having an environment that is conducive to development, not so much about any particular leader. And I think that is true in most cases, be it the "great sport coach" or the "great spiritual leader."
Of course the importance of getting humble when working with other talented people is obvious. Also the way it's important to have freedom and a good incentive to work between people. It worked very well so far... And in the same way, even though I created Matroska, I don't think I'm controlling everything. Just influencing, as much as the others.
