I agree that systems and libraries you don't deal with every day should strive for simplicity and learnability, but I think simplicity is a much lesser virtue in programming languages.

A programming language is something you use every day, so you'll inevitably invest time in learning it properly. A language you can learn completely in a few days is unlikely to give you as much power, convenience and maintainability as a more complex language. Choosing Go might get you and your team started faster, but wastes a lot of potential over time.

(Of course complexity on its own is not a good thing, some complex features may be prone to abuse, orthogonality is still important etc., but Go is way too conservative to be competitive long-term I think.)

To be simple is wrong, what is needed is to be minimal and to the point. Most of the time, the minimal tool is simple enough, but sometimes complexity is a necessary evil.

Driving a car is more complicated than running. Why do we invent cars in the first place?
