Industry clearly prioritises speed of delivery above all else. Security, reliability and maintenance are future problems (that would be nice to have).
However, in order to gain the power to reason about our code and be able to prove the correctness of various properties (what a typechecker does), we have to program with more restrictive models. This has been argued many times before (e.g. Dijkstra's structured programming). Haskell and Rust are just two of many examples. My favourite is regular expressions, choose actual proper regexes and you have guaranteed O(n) execution, choose Perl/Python "Regex" and you have a potential security hole.
