Lets look at Java in modern day.

* Most mature Java project has moved to Kotlin.

* The standard build system uses gradle, which is either groovy or kotlin, which gets compiled to java which then compiles java.

* Log4shell, amongst other vulnerabilities.

* Super slow to adopt features like async execution

* Standard repo usage is terrible.

There is no point in using Java anymore. I don't agree that Rust is a replacement, but between Python, Node, and C/C++ extensions to those, you can do everything you need.
