Weird article. Different users have different priorities and that’s what the CAP theorem expresses. The article also pretends that there’s a magic “load balancer” in the cloud that always works and also knows which segment of a partitioned network is the “correct” one (one of the points of CAP is that there’s not necessarily a “correct” side), and that no users will ever be on the “wrong” side of the partition. And not only that but all replicas see the exact same network partition. None of this is reality.

But the gist, I guess, is that for most applications it’s not actually that important, and that’s probably true. But when it is important, “the cloud” is not going to save you.
