I started using it _way_ before it was even mentioned in AI projects. The key reasons I stuck with it were: 1. As a Pythonista, I _very_ much like its batteries included philosophy (I get proper Typescript, SQLite and a lot of goodies out of the box without hundreds of crufty NPM plugins) and 2. The tooling is awesome: a decent bundler, ability to build "single file" executables, etc.
If you think it's popular because of AI, think again.
