80% of AWS existed before Go was invented. Why would they rewrite that stuff? They're already #1. They have nothing to gain and everything to lose.

I think to get an idea of what mindshare looks like, you have to look at people that started from nothing today. These are the people that are making architecture decisions with an eye to the future, growth, and immediate productivity. When you're inside a huge org, you have to think about what is easiest to integrate with, and what skills you can get from other teams. At a company that's 80% Java, that's Java. It would be insane to switch, and likely to fail.
