IMHO the keyword is 'microservice': Compile times of 30sec for a microservice are not acceptable for me, btw. The projects I am referring to were bigger, and the time to compile/open projects in IDEA where _not_ acceptable at all. (Btw.: I am speaking about Scala experts, not some new grads which didn't know what they were doing.)
Concerning your type erasure example, the id function obviously doesn't need to know anything about types. In the real world, types have traits/interfaces/expected attributes etc. and type erasure prevents the compiler to verify this when using binary dependencies, which is obviously _not_ what one wants in a statically compiled language.
