To be fair, they didn't say Java, they said JVM. That allows Kotlin, Scala, whatever.
Java is missing so much and has so many design errors (which are acknowledged as errors), I agree that it should be avoided.
I think Rust is a better language, but you can't exactly incrementally convert your Java codebase into Rust very easily. If you stay in the JVM, things like that are much easier.
Care to explain why? I get that there are some horrible Java projects and libraries that have really ballooned in complexity over the years but I still see Java itself as one of the better languages. Especially for corporate work.
Rust is the future but not mainstream and still early. Can’t wait.
