While reading this thread, it feels like a flashback from 2009 and now, I remember what was my biggest gripe with Rails (next to all the bad parts mentioned here in this thread):

It is the culture.

I really find the Rails culture odd or tbh, I utterly dislike it. I mean if met a Go guy, he tells me all good with Go, it gets the job done but it has its warts, the same with Rust, node, React and so on. People of other stacks like their stack but it's not about life and death. Only Rails guys have these issues and would start a flamewar right on the street and try to evangelize, yell at me why Rails is (always) the way to go and imply that I am not just wrong but also an incompetent developer. There were so dogmatic and when reading such posts in 2019, they are still this way.

Edit: as expected I got downvoted and this is what I mean, they take this too serious, Rails is their religion, Rails locked them in. Downvoting doesn't bring your Rails back.
