alt Hacker NewsSurely there are some!
I think AI is the obvious one. Also, VSCode (or whatever modern IDE you use) is definitely better than the IDEs that existed 20 years ago. LSP is fantastic. Hm... StackOverflow was definitely a step change over existing tools. Godot is really good, much better than anything that came before, IMO. Modern languages are pretty good these days - Rust and TypeScript are better than languages in the 2000s, to name two of the top of my head.
Quite honestly if you put ai aside and just look at VsCode and typescript which is a common drug of choice these days the Java plus Eclipse of 20 years ago was the superior toolkit. At least semantic search and refactoring worked reliably.
