Yo Matt,

I've been in the Ruby on Rails game for twenty years. For the last ten, Rails has been declared deceased. ;) But in reality, Rails is still going strong. The jobs are highly paid and fun. All the pros you list are valid. Yes it is a beautiful language, the OO makes sense, it's dynamic and expressive, and the ecosystem is top shelf. What's to dislike? There are a lot of Rails websites out there. And new ones get created every day too.

Now, to address the elephant in the room....

Ruby is quirky. Since the syntax is pretty different from PHP, and core developers being opinionated, some people just see drama. When Node.JS got slightly usable, they moved over to that. Node.JS is very c/PHP-like after all in its syntax. Many engineering managers will just select the ecosystem that is biggest. Node.JS is a lot bigger. But if you don't care about going a little off the beaten path sometimes, Ruby in my opinion still, after all this time, gives me joy when I use it.

Also important: to this day, I can build everything I want. Ruby, Rails and many gems are being actively maintained. Security vulnerabilities are discovered and corrected. New developments still find their way into the language. For myself, I know that the anemic JS standard library would just frustrate me to no end.... every wheel is invented time and again. Ruby's standard library isn't as voluminous, but it's a lot more diverse and useful.
