People should. I seriously miss using it at my day job. It's not for code where type systems make things a lot more stable, but it's great for scripting and quick things. Also ORMs in ruby are truly nice, and I haven't found anything as good anywhere else.

Generally speaking Ruby has the best APIs.

Ruby on Rails is the GOAT. Nothing comes close in joy and productivity, even in 2026.

For pretty much everything. My terminal is in Ruby, with a Ruby font renderer, running Ruby shell, and my editor is in Ruby, my window manager, my file manager.

(Yes, I'm taking it a bit far; my prototype Ruby compiler is self-hosting finally, so I guess sometime in the next 20 years I'll end up booting into a Ruby kernel for no good reason...)

ruby and rails is the only stuff that keep me doing web development.

when I touch js, and python... I prefer ONLY AI agentic style of working.

What’s the right way to take this?

From the article: "This new feature will be available in Ruby 4.1.0."

Aside from the oddness of making this cache git aware, with the new implementation I suspect querying git to revalidate the cache would take longer than just rebuilding it.
