Eh maybe. I work on a big, mature, production erlang system which has millions of processes per cluster and while the author is right in theory, these are quite extreme edge cases and i’ve never tripped over them.

Sure, if you design a shit system that depends on ETS for shares state there are dangers, so maybe don’t do that?

I’d still rather be writing this system in erlang than in another language, where the footguns are bigger.
