I hear you. I use Cursor editor. I work with all of these technologies: Ruby on Rails, React, Next.js, Django, vanilla JS, jQuery, HTML/CSS, Tailwind...depending on the project.

I just spent the past week working on a hackathon where I built the project using a Node.js closed-source platform that uses Fastify edge functions and Cursor's autocomplete was terrible. Much worse than what I'm used to when Cursor makes autocompletion for Ruby/Rails code. JS libraries come and go every day. This makes it difficult for Cursor team to update their LLMs to provide good autocompletion. On the other hand, Ruby and Ruby on Rails have seen very few radical syntax changes. The syntax and majority of the API has remained the same.

Ruby on Rails is so much more than just fast scaffolding. The code I've written a decade ago in Ruby on Rails, I can still pick it up today and understand the project. I can also pick up anyone else's project and figure out the intricacies of it much faster than I'd ever be able to do in say Next.js or Express project. Express feels like writing assembly (no hard feelings).

I've, unfortunately, recently started working on a project that's written in Django. I thought Django is just Ruby on Rails for Python. Boy was I wrong... But that's a story for another time.

IMO Ruby on Rails is an absolute king! However, I'm looking forward for a day when I'll be able to use one language on both frontend and backend, while having the same simplicity and functionality as Ruby on Rails. (I'm looking forward for Ruby on Rails JavaScript successor, but it's just not there yet.)
