Martin from GitHub here. While Copilot is good it's not quite up to those numbers yet I'm afraid. It’s early days, but we’re already seeing that for some languages when people have it installed, we see about 30% of newly written code being suggested by Copilot. Vary’s between languages and the numbers of users in the technical preview is a LOT less than the 73m folks we have on GitHub, so a long way to go before it makes up a third of everything..
