Long-term problems with dynamic typing

This image comes from the preface of a book titled, “Haskell Programming from First Principles.” (FWIW, the PDF of that book is currently over 1,000 pages long, but it is good.) Personally, I agree with what the author is saying. In my own experience I like dynamic typing when I’m writing short scripts, but I don’t like it when I’m writing larger applications. That’s just an opinion, but it’s a reason that I prefer Scala over other languages.
