Worth trying if you’re on the fence, especially if you’re into static types, no nulls, functional, ML type languages. Plus beam of course.

For developing fault tolerant multicore programs I think I'm better off using a functional effects system with software transactional memory like Scala/ZIO than Gleam/OTP. I can still use the actor model where appropriate. Plus the JVM software ecosystem and runtime observability / battle-testedness is far better than BEAM.
