Well actually that's not true. You use the best tools for the job. Front end can be done in PHP/Ruby/Django quickly while the entire back-end can be written in java or lisp. It all depends on what you need and what is the fastest, most scalable way to accomplish it.
That is true intelligence.
In my eyes Good and Trendy vs Good and Not Trendy is irrelevant. They are both good, so solve the problem.
Oh and "rails does not prove your smarts" should be:
"Using technology X does not prove your smarts." because there will always be another X. Today its Rails, tomorrow its Open Sails, and the day after we all go back to Lisp.
