You’re thinking of architecture astronauts when talking about generics. The biggest win of the object-oriented folks was to get a garbage collector included by default; compare and contrast with Rust, which ended up not having garbage collection.

So, you’ve never known any Unix hackers? I worked for a student datacenter when I was at university, and we were mostly vim users; as far as text-editor diversity, we did have one guy who was into emacs and another who preferred nano. After that, I went to work at Google, where I continued to use vim. As far as fancy IDE features, I do use syntax highlighting and I know how to use the spell checker but I don’t use autocomplete. I’ve heard of neovim but don’t have a good reason to try it out yet; maybe next decade?
