Elixir vs Ruby on Rails

Not just harder, it often makes it impossible. How do you argue about old languages like Java producing programs 2 to 3 times slower on average than Rust (a language still in its infancy) equivalents? Surely Java, being waaay older and adopted by so many corporate behemoths, should have the advantage with its super optimised compilations backed by thousand of doctorate thesis. Something just doesn’t add up.
