It’s quite surprising when you update Rails and they have changed the arguments for some obscure function used in only one place deep in your app and you get no indication of this until the actual line of code is run and it blows up.
I’ve worked on rails apps for the last 9 years and I’d guess 80% of the bugs that show up on production would have been flagged by typescript.

Which is what the Ruby test-heavy culture is all about. I prefer types for this very reason; the compiler/checker is a complete suite of testing I don't have to write.
