Well if we followed this rule I think we'd all still be using punchcards? Or FORTRAN? It really depends on what your Enterprise looks like but I do agree that

Well if we followed this rule I think we'd all still be using punchcards? Or FORTRAN? It really depends on what your Enterprise looks like but I do agree that many corporations are going to be better served by more mainstream languages. That said, if you're worried about creating good maintainable software then types are the way to do it -- a lot of the changes that are landing in Java/Python/Ruby/etc came from the niche languages with the good type systems. The renaissance of typing (typescript, mypy, sorbet) is people essentially collectively coming to their senses and realizing that they want to know what their function is expected to be fed, at compile time.
