Lack of static types is one of the main reasons. Trying to decipher a complex ruby on rails codebase is unnecessarily difficult compared typescript. The tooling is also shit unless you use Ruby Mine.

An absolute shame given how good the functionality is baked into RoR.

I think the only thing you need is grep and know what you are doing.
