For a long time, I have been put-off by the cult of DHH, but at my current company we have a large "legacy" RoR project (among other stacks) and it could be useful/pragmatic to be able to work on that.
So I guess my question is, would it be a good effort & time investment to learn Ruby and Ruby on Rail for 2025, or that ship has already sailed?
I have learned many languages and tools in my career, many of which I only used for a short time. I don't regret learning any of them.
