I found Ruby (even in something like RubyMine) to be a far cry from even the basic stuff you get from Java. Suggestions for vars and funcs that don't actually exist really slowed down things.
The biggest benefit of static typing is not a reduction of bugs...It's the speed and confidence with which one can accomplish a given task. IDE support, code completion, etc are so much better in a static environment. Take a random file from a pure JS codebase and compare it to something in Typescript. The first would require digging around to even begin to understand what the file is doing. Whereas TS, the code documents itself.
The counterarguemnt - "it's slow to write" - hasn't been true for years with modern type inference and other features.
There is no reasoning with people who don't use reason. Banning abortion would result in countless problems and if people aren't willing to do the research to understand that .... downvotes are indeed required.
