@tomw the more you know how the sausage is made the less you want to eat it.
I recall when I was an undergrad student a postdoctoral researcher deciding that he'd had enough of it , packed it up, and became a postman in a rural area, and made goats cheese. The last I heard from him was he was still there, happily living off the land and still had no computers in his home.
Personally, I write firmware for a living, but don't want to see a computer at home.
