They mentioned it was a rewrite that happened in a couple of days in a shop that uses C++ and Python (at least). We can assume it was a small to medium utility program.
Someone who can write C++ and Python professionally will get up to speed with Go in a few days. This shouldn't be a hiring issue. The cost of rewriting it again in C++ can easily be higher and apparently was a huge PITA. Go is not some obscure language, it is literally designed to be accessible by anyone with basic programming experience.
As a programmer I agree, but as management that's a hard thing to tell. If you were the boss would you allow Lisp? Scheme? Erlang? It sounded like a pretty important piece of code, even if small. The complaints about being forced to do C++ and how painful that process was shows that it's at least non-trivial.
I disagree. If you're managing programmers, you might be expected to have a bit of a clue about programming languages. If you can't tell how easy it would be for your people to pick up Go versus how easy it would be to pick up Lisp, you have no business managing programmers.
