That's fair. I just don't have the same experience.
My hobbies are very similar to my day job (software engineer), but in a different tech stack (Python @ work, Rust @ home) and building different things (business logic @ work, distributed systems and games @ home).
Maybe it helps that I'm forced to use macOS at work (which I dislike), and I get to use Linux at home, so it really feels like separate things.
But then again, many of my coworkers don't have personal projects at home, so I'm probably just weird.
