I'm not a fan of dynamic typing at all (currently maintaining a decade's old e-comm monolith written in Ruby on Rails), but instead of arguing about what bugs are caught where, I've instead switched to arguing from a position of developer experience. The _tooling_ that statically typed languages have is levels above those found in dynamic languages. Runtime errors are runtime errors, but knowing at typing-time that the shape of thing A is what thing B needs is a huge benefit.
