I'm completely with you. Rails is still my go-to for short one-off projects that I need to build something FAST.

Hell, I even use it for quick n' dirty data analysis because working with Active Record is so easy. Rake import the data, then muck around with the Active Record models in Rails console. I honestly prefer this to working with Jupyter notebooks, unless I need graphing or something fancy out of sklearn.

"Rails can't scale" is a misnomer. Heroku and Github are RoR apps (or at least started there). At scale you might start pulling in some other services and technologies.
