This is flamebait but I would say no. Ruby's popularity has been in a steep decline for years now. The most rapid decline of any language tracked by stack overflow metrics. By some measures it's usage is less than 1/4 what it was at its peak.

Ruby is slow. And Rails has an outdated MVC web model when everybody is doing SPA. If you're building a SPA you don't need 90% of Rails functionality. And since Rails is the juggernaut REST framework, there's not a lot of other options.

The last thing is that Ruby's popularity has dropped so much that it's falling out of mainstream. This is kinda sad honestly, but it doesn't change reality. The most obvious example to me is lack of HTTP/2 support. The Rubyists will say "oh it's fine just put it behind a load balancer that does it". To me that's the same as putting your old mainframes in the closet so nobody sees them. Any other "mainstream" language has had HTTP/2 support for years now. Including Java which is notorious for doing everything last
