I used to get invites for jobs and see listings for jobs for Ruby and Rails a lot. Now I don't see any at all. There's most definitely a "dead" feeling to the platform.
I hardly hear about new projects being started with Rails as well...
It may be that after years of working on other technologies, you just aren't passing the filters anymore. When we were aggressively hiring Rails devs in 2021, we specifically searched for the seasoned Rails devs that could hop in and get going. I've found less appetite outside of the big shops (Shopify/Github/etc) to pick up junior Rails devs which isn't great.
Probably depends where you’re based. Ruby is still lucrative in London and there is a healthy market for it both in startups and more established businesses. While I’ve branches out to other languages (not just JS as a full stack engineer) my career is still boosted by my Ruby experience.
I don’t think this makes it dead or dying though. It’s stable and entrenched while JS has taken the place of the golden child.
One complaint I’ll grant myself is that library development is a little less prolific this days. Again, there are well-established solutions to a lot of problems in Ruby so you’ll have a go-to collection of gems, but it’s more often the case these days that something doesn’t have much library support and you’ve got to roll your own.
