I’ve recently come back to a big Rails project after doing React/TS for a while and I feel exactly the same way. I feel like we’ve learned a lot about what kinds of tools help make programmers productive and help them write correct code since the original Rails heyday and none of those lessons have been absorbed into Rails.

Rails is a reasonable choice if by installing Rails and some gems you’re already 90% of the way to your goal. Every line of code you write after that is another step down the road to unhappiness.
