> I don't think it was ever uncool because of the core language

Putting type-erasure vs. reification to side, I'm going to disagree here: for reasons unknown, Java's language designers have adopted a dogmatic opposition to class-properties (i.e. field-like syntax for invoking getters and setters), operator-overloading, or any kind of innovation of syntax.

I appreciate the problem of backwards-compatibility (and forwards-compat too), but the past 30 years of software and programming-language usage and design shows that field-like getters/setters (i.e. "properties") are a good and useful feature to have; so if Java is going to overlook something as basic as properties (pun intended), then it follows that Java's designers will similarly disregard other language design innovations (case-in-point: if "value types" are even an innovation).

I can say there is one thing that Java has done well, and that's make a good music video: https://www.youtube.com/watch?v=1JZnj4eNHXE

Yes, Project Loom's reinvention of Green Threads is cool, but that's not anywhere near enough to address Java's declining relevance and credibility as an application-programming language in the era of C# 13, Rust and TypeScript (and yes, I know Rust doesn't have properties - but the rest-of-Rust more than makes up for it). My main take-away from the past 15+ years is that Java fell-behind everyone else; it's not that C# is Microsoft's take on Java, but that Java is now a third-rate C#.
