Ruby’s biggest flaw is that it insists humans matter. Some people hate that.
Ruby arose and became popular because it caters to a niche that was underserved by the competitors of the time (and while I'm no historian, I think Rails had a big role to play in Ruby's popularity).
Ruby is very ergonomic, and so is Rails. Frankly, almost 10 years after moving on from it, ActiveRecord is the yardstick by which I measure the ergonomics of all other ORMs in other languages, but what ergonomic means will vary from domain to domain.
With languages like Ruby and Python, it's very easy to get from nothing to an app that will work generally well enough almost straight away. A lightweight syntax, a lot of implicit functionality, and a flexible type system are all great for that, but in my current niche, I couldn't use it (I currently work with Rust, and the explicit control is a huge selling point, despite the much heavier syntax and more complicated semantics). That doesn't mean Rust was built without the human experience of using it in mind, though, and arguably the opposite's true.
It is a joy to write Ruby, I’ll give you that, but it is a pain to live around other people’s Ruby at scale.
Back then, Ruby and Rails opened a lot of people's minds to the idea that we were allowed to make "delightful" a consideration in API design, not just S.O.L.I.D. or whatever. These days, there are way more mainstream languages, frameworks, and communities that take humane APIs seriously.
I certainly have written a great deal of ruby and have no strong opinions about the language aside from "I will shoot the next person who uses method_missing", but I find the people who do have strong attraction to the language endlessly fascinating. By far, the most human aspect of the language is the community built around it.
Uh how?
