Is Ruby on Rails Dead?

No, but my recent experience with giving Ruby an honest shake was that very many repos/packages are abandoned or of poor quality, compared Python.

Although a language never dies, I was surprised at the level of decay.

This is clickbait for no purpose other than advertising.

Seems like a marketing gag for https://gorails.com/

haha, you got me, nice clickbait title & domain for GoRails $19/month service.

eh? Fortran is not dead. How can RoR be?

Not dead, just mature enough that we don't need to talk about it, it just works.
