How did you get any of that from the comment above? I thought the elitism they were referring to is the the assumption that other jobs don't also have equally deep impacts on a person's identity and way of being.
The part about existing outside of work - that's just reality though. A lot of coders are just doing it to support their families, and a lot of them aren't doing a side hustle or side projects when they're off the 9-5. That stuff gets normalized and glamorized in the highly-compensated-engineering-for-cool-tech-company scene, but there really are working coders who don't do any of that and get by fine all the same. They just tend to live in uncool cities and work in uncool industries.
