This is one of the most absurd, black-and-white things I've ever read.
Does innovation come from running, showering, lying in bed? Absolutely, no question.
But at the same time, when you get a diverse group of people to solve particular problems, they generally come up with far better solutions than any one of them would have on their own.
Because these are really about two totally different types of problems. The first "private innovation" one is often about finding a clever solution to a relatively well-defined problem that is "puzzle-like" -- math, code, chemistry, whatever.
The second "group collaboration" one is often about finding a workable solution to a relatively ill-defined problem that is people/organizational/product -- what is the right marketing campaign, right new product, right new vacation policy? Where the most valuable contribution is "wait, but have you thought of this?" or "wait, but if we do that " and everyone says "oh good point, I didn't know that was a constraint/solution!"
The obvious answer is that both are valuable. The idea that they are somehow at odds, or that only the first one is "work", is ludicrous. It's true that "individual contributor" jobs often fall more into the first category. But to denigrate the second category as "not work" is both disrespectful and, frankly, just idiotic.
