Done Rails my entire career. It scales more than you think if you’re willing to throw some hardware at it and avoid turning your controllers and models into logic layer soup. What kills scaling is inexperienced developers doing what I just mentioned. Also, ActiveRecord is not your friend at scale. It’s wonderful in small amounts, but callbacks and memory overhead will kill you. You really need to learn SQL to avoid doing select * on seven tables. Also, view partials. The lookup cost on those is pretty high.
