Google also has a gargantuan-scale dev team that includes the people behind Go. It's ridiculous to compare. If Github does not yet themselves have sufficient people with sufficient experience supporting large services in Go, betting critical infrastructure on it would be irresponsible.

Note that he is not saying they're not open to alternatives, nor that they're not experimenting with alternatives, but that they need more experience first before "betting critical infrastructure on something else by default".

It's not ridiculous. There are probably reasonable arguments against using Go for things like this, but "insufficient developer capacity" isn't one of them. Becoming a Go expert is a task measured in weeks.
