I don't think anyone should really believe in Rails at this point. It was a monumental leap forward at the time but other stacks have shown that there are better ways.

I learned Ruby in 2007 people have been saying that about Rails every year since

I love Elixir/Erlang but we all know the "better stack" these new devs will choose instead for a web app is a maze of React, supabase, and Auth0.
