advanced work != advanced tools
You can have basic and not very user friendly tool, and work on very advanced topics, such as new forms of networking, innovative database, cool filesystem or storage devices, etc...
Or you can be an advanced windows developer with very nice tools, and yet work on something utterly mundane, like an internal app which tracks time off in your company, schedules delivery of parts, or provides a (granted, very nice and polished) UI to the backend database server which runs Linux.
In my experience, most of the advanced work is done on Linux nowadays. Just look at HN front page - how many posts are Windows-only and are not "new UI over existing library/service"?
Windows does plenty of 'advanced work'. Almost all video games are written primarily on and for Windows.

That's because your experience probably hasn't ever included work on Windows internals. Take it from someone who has—the complexity and 'advancedness' of the stuff running on Windows is at least equal to that of Linux or any other OS. The fact that Windows can so thoroughly abstract the computer away from the user is in itself a massive feat that few other OSs have really managed.

The overwhelming majority of posts on the HN front page are now LLM slop or web development. I seriously dislike this insinuation that work done on Windows is, as the grandparent claims, 'unserious' or less advanced.
