Yeah I mean I think this is the crux of the matter here. That and the fact that most conferences are an exercise in circle-jerking about how smart you are.
Well I would say their philosophy first of all relies on strong tools. Intellij with CHelper plugin allows for simpler testing and also has incredibly powerful debugging as I am sure you have seen in their screencasts.
Also I think they sort of show the value of Java's simpler approach with everything being a reference in terms of writing code quickly. The alternative approach that C++ competitors use relies on a very specific style unlike what production code at say Google uses, with pointers used as sparingly as possible. With everything being a reference it is much easier to work with graphs for instance.
To me Rust goes even further into the C++ direction where it becomes more and more difficult to quickly write code that compiles. With Java I have no issue writing 100 lines and having everything compile the first time around, particularly with an editor like Intellij. With C++ even Clion struggles significantly with producing helpful info, simply due to the complexity of C++.
Anyway don’t have enough time to really eloquently think through all aspects of this. Also I was just kidding about CF rating, you are far better than me obviously.
