For example, I learnt C before C++ and found coding in C++ was more enjoyable than coding in C.
Since then I've been doing a lot of C# coding and I find that much nicer than coding in C++.
From what I've seen of Go it's seems quite a nice language. So by getting proficient in Go it might actually be too frustrating to then try and start coding in C/C++.
Now I don't consider myself an expert in C/C++ but after writing and debugging that many lines of C/C++ code I do consider myself proficient.
But that doesn't change the fact that when it comes to languages, I find that C# is easier to work with than C++.
But that is just my opinion.
But there was one full re-write in that time.
The goal of a programmer should be to write great programs.
Sometimes that may require discovering new paradigms. Mostly it involves picking up a trusted tool and getting on with it.
Studying programming languages themselves may make you a more knowledgeable programmer but will not necessarily make you a better programmer.
To become a better programmer you simply have to write better programs.
I find the backlash against my view sort of ridiculous to see on "Hacker News." This is really not that controversial.
Who said you have to learn every junk language under the sun?
