this is pretty abrasive, but it's also 100% correct. before you downvote this you should take the time to investigate the claims it makes and think about whether what you think you know is actually true

i learned a ton about distributed systems in my time writing erlang and elixir, but it was almost always because i was forced into it by misapplying some erlang/elixir feature and backing myself into a corner. the idea that erlang/elixir make concurrency easy is extremely dangerous. what they do is make it accessible. you still need to understand what you are doing
