Desktop dead. That would be a nightmare scenario for me as I much prefer coding desktop based apps/games compared to web things. I code web things professionally. It's where the money is. But the fun is in desktop/mobile/console apps/games.
It would be more precise to say: Desktop business apps are dead. That is almost 100% true. Some lingering ghosts still exist.
At work we are replacing a huge app which had a C# UI with a micro service based app with a React UI.
While the backed is nice, that React UI feels like crap compared to the old UI. The only reason we are using an React UI being that "it's modern".
Not every app should be an web app.
