Anecdotally, I'm also seeing more and more traditional organisations move from "corporate world" frameworks (Java, .NET etc.) to RoR because they are seeing how fast smaller companies and startups that use RoR are able to get things done. Probably also a side effect of how much people from the startup world like to brag about how much they can "get done".
Though as a result of people seeing how fast you can get things done in rails, I've seen a lot of really poorly coded rails sites which does hinder progress. However I think that is an inevitable outcome of any good framework - if you make it easy to get the boring work done then that will have two effects:
1. it allows good developers to skip over boring or repetitive work and focus their efforts on hard problems.
2. it allows inexperienced or just plain bad developers to churn out applications which may get the job done but the code will be a mess.
So yes if you enjoy coding in RoR then I see no reason not to stick with it. However I'd suggest you pick one language/framework and stick with it. This might not be an opinion appreciated by the hacker news crowd but the reality of getting work as a freelancer is that most managers or potential clients will be more impressed if you can say "5 years experience with Ruby on Rails" rather than "5 years experience as a programmer - working with Go, Rust, Node.JS, Ruby on Rails".
As a developer, however, my opinion is very different. I've been doing Rails work for about ten years now and while in the beginning it felt great, I see it now as a big liability in terms of long-term growth of a project. "Just add a gem" is neither a good scalability nor a good growth story on a project.
web2py is where I finally settled after trying Django and Flask first. It's got more magic in it than Django, and yet, I found Django felt heavier and more "over-engineered". Flask, on the other hand, is very elegant, but as soon as you start patching together a few different libraries, the cognitive load of needing to understand Flask, WTForms and SQLAlchemy was too much for me.
web2py has most of the features of Django, but is written by only 1 person so the API is much more consistent than a Flask-based smorgasbord. It took me a small fraction of the time to get up to speed on the web2py documentation than it did for me to figure out the Django and Flask ecosystems :) I recommend it whole heartily!
