Um, he may have made a significant "observation" as you call it, but it wasn't his idea to research VOIP, to go out and get a device, or even how to implement it in a functional way to enact the advances in technology in a meaningful cost-savings avenue. It's right there in the article:

So in this particular instance, he's much more akin to a record producer creating a hit by lifting samples from other artists and then rapping about himself over the track. You might see it differently, that's fine. I just don't buy the self-directed, "Look what I made" narrative being put forward as fundamental here. Oh sure, it's his "vision" and all, but vision without talent and skill is just daydreaming. So he got some real people do to the hard part, that's a great "leadership" example I suppose.
