The issues mentioned are largely addressed by jshell and lambdas.

Regardless, his issues mostly boil down to "Java is not a REPL-first and Lambda-first language". This is like me "hating" my cat because it's not a dog.

I find many beginner programmers like REPL langs. When I talk to them, though, it becomes apparent that they've never worked on a code base with 100k+ lines with tens of colleagues.

One guy actually suggested that systems should never be that big! What do you say to that? I just smiled.
