I understand where you are coming from, there are certainly cases where there is too much flexibility and there is a general need for better quality culture, always writing unit tests with good test coverage, etc. Not all languages do it well and many could benefit from some extra optional compiler strictness. However, you still have comparable bug rates for both very expressive dynamic high level languages and lower level ones, making quite a big difference in total number of bugs for the problems of the same complexity. Basically having to write say 3x less code in something like Perl than in Go, to solve the same problem leaves you with 3x less bugs and takes a lot less time.
