> If you only know java are you even a real (professional) dev?

I'm a polyglot but Java is the language I used the most and I can guarantee you there are many professional dev I met and worked with that only know Java and make their comfy living writing only Java. Java is powering the real world since more than two decades now and the JVM is some rock solid tech with extensive tooling, so they can get away with only knowing Java.

A dev can definitely focus only on Java and, for better or worse, makes all his career, from his first job until retirement (to me it's obvious Java is here to stay and it's going to dwarf COBOL's legacy), writing only Java.

Nobody said frauds can’t live comfortably.

Why on earth would somebody earning their pay by providing value and doing the job they were hired for be a fraud?

Not all programming jobs require a PhD in computer science. There's plenty of people out there writing line-of-business software, and that's the stuff that makes the world work.

Sorry, poor choice of word. I meant dilettante, not fraud.
