How many times is this gonna get reposted as some sort of gotcha? He's right, and having to deal with juniors or large teams with varying competence isn't unique to Google. I've met many devs who praise Java for how simple it is to parse through for people of all experience levels (once you get used to the verbosity). In fact, two of Java's founding principles was that it had to be simple and familiar. Yet I don't see anyone pretending that's a bad thing.

Go has the same goals, just a different approach. Java is too verbose, Go takes the simplicity approach too far sometimes. Neither are perfect but they're definitely useful and worth considering for many projects. The fact that it was made with juniors in mind is a plus.
