I love Ruby too. It's a great language, and as a language I like many things about Ruby a lot more than python. In particular, chains of functional operations like:
arr
.map{|o| ... }
.reject{|o| ...}
.reduce(init_acculm){|init_acculm, o| ...}
are super super clean and expressive. Very similar to what I like about Java streams.
And the library ecosystem is great, I like how it shares spiritual similarities with python where libraries are very "no nonsense" (you don't need extensive configuration and builders and researching a million configuration items etc etc... looking at you, Java) and you typically just import and go. Rails, of course.
I keep picking python over ruby though, for things I'm going to have to actually maintain. And I typically pick Java over python if I smell I'm going to care even an iota about performance. (Often I don't, though). But ruby vs python, I keep coming back to the divergent opinions they've taken on gradual typing. I like that python3 lets you include the types as part of the program, part of the grammar. Ruby relegates them to a separate file. I guess the intent is that it's more for libraries, like how js libs will ship typescript type files? But I don't like that, I want types for myself. Sorbet exists, of course, but I don't like that it's a) a gem and b) still not a first-class part of the grammar but is instead just operating "in-language". I know it works and e.g. Stripe uses it to great effect (I worked there) but I just don't like it, personally, and I find that python3 with its built-in type hinting tends to get typed more readily than ruby where it's a much further reach away.
But I really love ruby. I hope it improves its type-hinting story because I like most other things about it. But I was pretty unenthusiastic about python prior to it getting its type hinting built-in, so apparently this is a big deal for me.
