I was in a platform team using Pulumi (TypeScript) for a while. An issue I observed is that the team members with weaker programming skills were contributing not so great changes, and parts of the codebase diverged in style. The Output type also took some time for us to get our heads round and it felt awkward to work with, we were having to chain a lot of calls and had callback hell sometimes.

We were all experienced with Go but at the time the Go SDK was very awkward, although I think some of that has been resolved with generics now. TF is less expressive but I think that’s actually better for 99% of cases.
