Android predates Go. And it wasn't even started by Google.. Android was it's own company and had already made it's decision on Java well before Google decided to buy it.

Not to mention Go is focused on a different use case. Go is gunning for microservices (with it's concurrency chops) and CLI based tools (being a single compiled binary).. whereas Android apps are a totally different beast that stands little to gain from either of those. In fact shipping multiple binaries for different architectures is a bit of a detractor for Android considering it supports MIPS, ARM, and x86.

> until I realized Al-*-Go was not actually written in Go!

Again, AlphaGo was based off technology from DeepMind, a company Google acquired.

Please atleast do some quick wikipedia browsing before spewing FUD.
