I agree that at large scale, types are one of the few things that keeps a project from completely falling apart (and I love lisp, but I would have a really hard time convincing my colleagues to adopt a dynamic language), but this seems counter to that:

> I've told co-workers to just any type anything they can't get working immediately and I'll fix it in code review

If you’re co-workers aren’t able to work with the types, how can they receive any benefits?

Not everyone is at a hyper growth place, but those that are would have zero luck with this pattern.
