I never, ever bothered to learn React or .NET/C#.

Stuck with C/C++.

If I have to write web UI, I don't.

React and .NET/C# made sense to me but are nauseating abominations of mediocre corporate tech, and the more I saw people using them, the more it reconfirmed my belief that they were a no-go.

Usually, people win if they do the opposite of what the mass is doing :)
