Let me disclaim by saying I like Python, and I've used it for a decade and it pays my bills. The author claims that Python has the lowest developer cost. I used to think that was true, and maybe it is in data science applications, but I regularly find that I'm quite a bit more productive in Go than in Python (largely thanks to the type checker and other static analysis tooling). As an added bonus, Go programs are regularly 100 times faster than Python programs, and usually Python programs are much more difficult to optimize than Go programs. Library availability notwithstanding, starting new projects (of any significance at all) in Python is looking like a worse and worse choice all the time.
