Elixir gives you the productivity for humans and machines alike without the performance costs. Plus you get 25+ years of Erlang battle testing as a foundation.

Everyone who once upon a time sneered him, should apologize to Zed Shaw. He wrote about all this in "Rails is a Ghetto" and the DHH lapdogs attacked him for it.

You're not any wiser today.

My opinion of Rails as a side observer: it allowed to cut coding time/effort/skill very significantly at the expense of performance. In the era when coding is dirt cheap thanks to LLMs and CPU and RAM are expensive, i don't see where the value is.
