Technically I don't think "author of article says they can confirm that numbers they used in their article are accurate" really holds up as a valid argument ;).
Tongue-in-cheek feedback aside, congrats on all your achievements and good luck on your future projects!
Anecdata: I've been doing all my projects in Go for many years now. My current production backend with 20+ services all run in Go on Kubernetes and serve 100k+ users.
It's an amazing language since it's so productive. Sometimes I write services in on go (pun intended) for an hour and after turning it on it just runs. Never experiences something like that with another language.
It's also very low on resource consumption. My server barely needs anything to serve that many users.
