Yet TS is massively popular. So maybe that’s not the only value?
Also what's good for enterprise isn't good for everyone.
I get that orgs probably like TS so that newbie devs don't do crazy things in the code, and for more editor hand-holding. But it's not valuable for everyone, if it was actually better than everyone would be using it, not just some people.
I've learned by hard experience that past me was an idiot and future me is clueless. Types are executable documentation that I can leave behind for future me so that future me can get instantaneous feedback while refactoring the project that past me wrote.
This is just a rehash of the discussions people were having about Smalltalk/Lisp 20 years ago... All the Java/C++ IDE people who were wondering how people survived without those tools, forgetting that Smalltalk/Lisp have live-coding, REPLs, and their own tools. Ruby is the same, the terseness + REPL/live-coding makes it easy to be productive and write bug-free code.
I know I'm far, far more productive in Ruby versus, say, C++ or Odin (my newest hobby language).
