python has mypy types and most places are switching to typescript over javascript. If you work with more than a handful of developers (and as such on a project large enough to require them) not having types DRASTICALLY decreases productivity.

Yeah you just end up with race conditions everywhere causing corruption and data loss. See active-model-serializers 0.10.8 release that just found a race condition where serializers would share state across threads making the default Rails web server (puma) completely unsafe.
