Reminds me of the School -> Pro pipeline where companies sell cheaply or even give away their software to learning institutions so that students who go pro are familiar with their tools and then later recommend it for their work.
- Java is cool, actually
- Java would be just as uncool even if people weren’t required to use it in school
Large enterprise doesn't value "creativity" or any deviation from standards, but it does value plans and estimates - hence clueless, brainless "managers" and "architects" forced programmers to do absolutely insane bullshit busywork that a gang of monkeys on LSD could do, and that culture spread throughout the large-enterprise world.
On top of that come "design by committee" stuff like CORBA, XML, SOAP, Java EE, Enterprise Beans and everything associated with this particular horror show, JDBC...
You can do absolutely mind blowing stuff with Java and the JVM. But fuck corporate for torturing Java and the poor sods tasked with the busywork. Java got the image it has because programmers want to be creative but could not be so because their bosses were braindead.
I don't think it was ever uncool because of the core language, it was always uncool because of the standard libraries, UIs and culture.
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#.
There were other products aiming to be just as good at the same time that were actually protected with dongles and such.
The one that everyone could run at home is the one that took over the world.
