I'd say 100% developer churn is the real problem here, no inherited 100kloc codebase is going to be a walk in the park if the original devs are not around.

However, I do think that it harder to keep a large code base understandable when using a dynamic language v.s. a statically typed language.

Having problems with understanding the shape of expected data is certainly a problem experienced in larger Clojure code bases, I guess this is just a disadvantage of using Clojure.

Documentation, tests, spec/schema and good naming conventions can mitigate this disadvantage to some extent.

I found some the advice in this blog post useful: https://tech.redplanetlabs.com/2021/06/03/tour-of-our-250k-l...
