And I agree on that. My favorite Elixir's runtime (Erlang's BEAM VM) still has some subtle problems with holding on to big(ger) binaries (strings) that requires very specific code be written at the green thread boundaries and it can get pretty maddening if you don't get it right -- which is not easy.

Golang I hear is doing much better btw. But you still have to be wary of its footguns i.e. leaking goroutines.

Go is doing much better on memory use because 1) it is AOT compiled, 2) it tries to allocate as much as possible on the stack (escape analysis), 3) it supports value types (the items of an array and the fields of a struct are contiguous in memory). But it's still a GCed language, which generally means a slightly higher memory use, controlled by $GOGC, to not spend too much time CPU time on garbage collection. Overall, Go is an excellent tradeoff for most applications.
