The problems with both stem from things like lack of (behavioral) tests, and lack of cohesive architectural principles (SOLID - what's that?). There were always "good reasons" for those problems being introduced and kept. Sometimes, there were attempts to "fix" the bad patterns that were root causes of bugs, but they were likely short-lived attempts before the team had to focus on shipping features again. Static typing often means people skip tests and that can lead to an untested, incomprehensible system that correctly passes types. Also, strong typing and dynamic typing are not opposites. https://wiki.python.org/moin/Why%20is%20Python%20a%20dynamic%20language%20and%20also%20a%20strongly%20typed%20language https://wiki.python.org/moin/Why%20is%20Python%20a%20dynamic...
