My friend was a pretty accomplished academic. Nothing like a mad genius or anything, but pretty excellent and capable. Wasn’t down with the rat-racey pressure to publish and oversell ideas.

I would definitely go for Irish sheep farmer. You get to live in a cute little house in a green pasture by the seaside and the sheep feed themselves. What do you need to do? Sheer them every once and a while? I'd take that over Terraform any day of the week.
I can see how decades of working at Microsoft can turn someone into a goose farmer. I've been using their products for decades and some days I never want to see their products again.
