also, if you step back, Ruby's problem is it consists of a fading community of millenials and Gen Xers who first came to Rails when it was the best/coolest option. however with the majority of builders now turning to JS for web, Rust (and Go) for systems, and Python for ML, it doesn't have a use case anymore that can drive a community or any hope for growth in the future. so a "niche DSL" for legacy webapps and plugin systems is what's left IMO, but i'm sorry for being super frank about it
languages like this with a shrinking community and loose security policies pose around the centralized package management system pose high security risks to its users.
