I'm curious how much Java needs the tooling in an all else equal situation (totally possible 'cuz Java is _old_) vs how much Java has all this cool tooling that enables/encourages people to do things that aren't possible in Go but which require the tooling. I've mostly used the Java, C++ and Go in my career, and it's pretty amazing to me that I can write write safe, readable code (like Go) on top of high-performance libraries (like C++) and step through code on a prod machine with a remote debugger, get live performance metrics with a single CLI command, etc.
