Ask HN: Worth Learning RoR for 2025?

Do you think it would be useful to learn Ruby + RoR when you already use Node.js, Python & Go ?

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?
