> If I launch 50 threads with run away while loops in Python, it takes minutes to laumch and barely works after. I can run hundreds of thousands and even millions of runaway processes in Elixir/Erlang that launch very fast and processes keep chugging along just fine.

I'm not sure that argument helps your position on threading. I once saw a java program spin off 3000 threads doing god knows what. Debugging the fucking thing was impossible.

The point there is that processes in Elixir and Erlang are effectively like functions, in that you do not need to "manage" them in any sort of way. They are automatically distributed across all cores, pre-emptively scheduled, killable, have a built-in inbox, etc. One doesn't need to worry about what concurrency library to use nor manually create mailboxes using queues or whatever else. It just works, and you fire them off to do whatever you need. So there is no ceremony. Threads in many other languages and in Python in particular, require a huge amount of ceremony and management.

I think Java made it quite easy to spin off threads, and again, it doesn't help the argument. It just made the f'ing thing worse. Race conditions are still f'ing hard to solve. Particularly when a shared-mutable-state exists outside of the program.
