I've been programming for more than 20 years. I've learned many languages including C, Objective C, Java, Python, Ruby, JS, and some Haskell. I've never worked at Google.
Go is my favorite language of them all and has been since I started using it almost a decade ago. I use it for personal projects, and I use it at my company.
It helps me and the teams on which I've worked write correct code quickly the first time. The code we write is incredibly reliable in production at scale. It's easy to read and debug years later. Binaries can easily be compiled and deployed on any system without messing with dependencies or cross-compiler toolchains.
The same properties of the language which helped Google have helped me and many thousands of others as well.
