Nowhere in this quote are these fresh grads equated to "lousy programmers", though (which the flamebaity comment did).

And interpreting the quote charitably I'm going to have to agree with it - I don't think many of my coworkers care enough to get to the point where they'd appreciate everything something like Haskell can do for them.

The more time you spend in software engineering the more you realize that this is actually brilliant and helpful, not bad. And IME, the more expressivity I have fluently at my disposal, the more complexity I tend to create. I’m not saying I don’t enjoy more complex languages, but reducing cognitive load and easing collaboration with more junior engineers are easily the best features of Go, hands down (although I can’t say the new generics necessarily always help with that).

That's one interpretation but I think Pike was using a sarcastic meaning for brilliant. I think he's saying that he wants to mentor people to become programmers, not to learn a difficult, sublime language. It's like when a top scientist tells you they're not smart enough to understand what's going on in some part of his field. It's not necessarily a compliment.
