Linus Torvalds with a banger
The creator of Linux and Git has no patience for rules about which tools you're allowed to use. His email speaks for itself. Plus a few thoughts on why new tools feel like a threat once the rituals have quietly replaced the goal.
Linus Torvalds, the creator of Linux and Git and much more, posted this to the Linux kernel mailing list this week.

We're moving through a time of transition and rapid change, and people have a lot of feelings about it. That's natural, and some of those feelings are quite justified. Others less so.
A lot of this comes back to first principles, which I wrote about yesterday. Keep your eye on the goal and a new tool is easy to judge. It either helps you get there or it doesn't. Once the rituals have quietly become the goal, a new tool looks like a threat.
I've made versions of this argument about writing and about my slides. Linus said it better, and with more capital letters.
