Tribalism is social nonsense. I taught myself C in 92 and Java 1.0 in 96. That Java was extremely verbose compared to C for chaining calls or just normal method calls. Rust is also verbose for constructing types and performing type manipulations. C is verbose for getting things done because of its low-level nature. As productivity and safety goes, I'd choose Rust over Java or C as a systems language for most purposes. The JVM is a secure foundation for running applications in multiple languages. Clojure, Kotlin, JRuby make excellent replacements for the Java language while still on the JVM.

JVM and CLR runtimes have an enormous amount of production experience baked into them. BEAM also would be fine.

It's a toolbox with tools that are better suited for some jobs than others, and it also depends which ones a group of developers know.
