I actually think Go is a very good language. I don't measure languages on aesthetics, but team productivity and quality. Go has been unreasonably successful in making my team productive.

I tend not to care all that much about the language itself. What I care about is productivity and that I don't need to have a discussion about what language people would rather program in every 3-4 months. This is why I get suspicious when people say they are language enthusiasts. I leave it to the team to choose language, but it has to fit some minimum criteria and I don't want whining afterwards and I don't want a mishmash of languages "because it fit the domain better".
