Ruby and Rails work perfectly well for many many people, and you have chosen not to be one of them. That's a valid choice, but it's your choice and nothing more

Ruby and Rails work perfectly well for many many people, and you have chosen not to be one of them. That's a valid choice, but it's your choice and nothing more. It really isn't much about Ruby or Rails. I grep through Rails code bases all the time. It is my first-choice method of discovery. In the very rare cases where it does not work immediately, I set a breakpoint and run from the REPL. This never does not work, even in the GitLab code base. I have my criticisms of Ruby, and Rails, too. But your "near zero" comment is a shallow dismissal that captures your biases and presents them as some kind of informed truth. It is not.
