Guess what? Wheels have been round for a really long time, and anybody who "reinvents" the new wheel is generally considered a crackpot. It turns out… - Linus Torvalds

The desktop hasn't really taken over the world like Linux has in many other areas, but just looking at my own use, my desktop looks so much better than I ever could have imagined. Despite the fact that I'm known for sometimes not being very polite to some of the desktop UI people, because I want to get my work done. Pretty is not my primary thing. I actually am very happy with the Linux desktop, and I started the project for my own needs, and my needs are very much fulfilled. That's why, to me, it's not a failure. I would obviously love for Linux to take over that world too, but it turns out it's a really hard area to enter. I'm still working on it. It's been 25 years. I can do this for another 25. I'll wear them down.

I was thrown out of fourth grade because I couldn't write my own name, and it's been all downhill from there.

But I much prefer other people solving my problems for me. So me having to come up with a project is actually a failure of the world—and the world just hasn’t failed in the last 20 years for me.
