Seems like a no-brainer to go with python for the long term. Why would anyone take the time to use this?
Because the author likes Elixir and its trivial concurrency story. But they also wrote the above: Use what you want, for them it's Elixir. Why complain about other people's preferences when they aren't actually foisting it on you?
No one should be learning Elixir solely for the purpose of writing short, one-off scripts, though.
Which isn’t to say the change isn’t welcome or not needed. Just that the limitation was overblown in most cases.
Another case, if your code base is in Elixir, picking an unrelated different language (python) would (IMHO) be as silly a decision as picking elixir for scripts when you have a python app, and I would strongly question that person's judgment and fitness for making sustainable and maintainable technical decisions.
1. you prefer functional style languages, such as elixir 2. you want to avoid `pip install` ing dependencies
