Bluntly? Because working with y'all is becoming insufferable. Because I don't want to work in IT. Note this isn't "I don't want to program" or whatever. That's cool and fun. But the people in here? Oh gods.

Also I'm sick and tired of working on projects where the best social benefit from my work would be if I stopped. And IT has this talent of doing this to even most superficially useful projects. I worked on solar panel software that got turned into a scam by marketing. That takes a talent, of sort.

The best time to jump out of IT was to never get into it. The second best time is now.

As for why barista? People need food and drink and coffee is great.
