Java doesn't contain conceptually difficult features. In Rust you have to learn lifetimes and borrow checking, in Haskell Monads... Java just has a huge amount of relatively simple features. Lisp is middle of the road conceptually, but is a small language. So in that sense I agree with you. Java is favored by people who struggle to learn harder concepts. That's why it's the usual target of the lowest common denominator programmer and loved by large enterprises that can churn Java programmers like mackerel.
