This, some people recently forwarded a "tech pay" survey to all dev teams (ours does C++/Qt desktop software), and there was only (basically) "Frontend dev", "Backend dev" and "AI/ML dev" in the job list.

It reminded me of that KotH skit "- So, are you Chinese or Japanese? - Huh, I come from Laos and... - Chinese, or Japanese?".

Crooter: "So tell me about your work at XXX Robotics. Was it more front-end or back-end?"

Me: "It was robot control software. It controlled a robot. Also I did some UI work, based on the same framework as the control software itself."

Crooter: "Ah-huh, and which database did you use? Oracle? MySQL?"

I feel the opposite. Sometimes I feel non-web developers don’t consider web devs as “real devs”, esp. the frontend ones.

This is an extremely mild version of what it feels like to be a minority. Web developers are the most common type of developer. It is simply natural for them to equate "developers" and "software developers". Out of sight, out of mind. It's not a hostile thing, it's not something people necessarily want to do. But it still happens. It's a human thing.
