I agree, but this is how most devs operate. Especially MacOS devs. So the great side of this is DHH exposing people to what is possible in an OS that isn't controlled by a top down corporation.

As a long time Linux user I'm not interested but DHH showed what is possible with a highly opinionated set up based on his preferences. MANY have done this before but he is more prominent. I think it will stick. More people will be on Linux and I think that's a win.
