I think the intent of saying "you've always been writing Go" was along the lines of "you can write FORTRAN in any language." E.g, implying that you are not making use of Python's abstractions, but writing it in the same procedural style you would write Go (or C) code in.
That is exactly what I am saying. I not talking trash about Go. But if one isn't using Python for what it is good at, don't use it, use the language you are actually using.
