I personally don't really care how easy it is to write a "hello world" in Go, nor Python. My day job involves big projects, so I'm pretty fine with "hello world" taking 10k lines as long as it will scale slower with complexity than other language. The same argument about learning curve -- I would be happy with a language that requires couple of years of learning to even start, as long as it takes less time in the following 20 years I'm going to be using it.
