One thing I haven't seen being discussed is the BEAM internals becoming a little long in the tooth. We still have static reductions before the scheduler switches to another task, the priority system in scheduling is a bit dodgy, flipping vmargs is kinda complex, lock counting and crash dump tooling kinda suck, etc.
BEAM is great, although it's definitely missing something like pprof for go or java flight recorder.
