A nit, but Ruby on Rails isn’t “old”. It’s mature. It still receives regular updates and release, even major version releases.
What it isn’t any more is new or trendy. Still pretty widely used though, and with good reason.

I don't know if I'd call that "mature".
As far as new apps go, yeah I think it's still pretty optimal for a huge swath of web apps, especially for early incubation when you have <20 engineers and you need to move quick. Not if you need web sockets, or other concurrency / performance critical applications though.
