One of the fundamental problems of distributed systems is the network. Adding a computing component over a network adds all kinds of complexity. Adding data on top of that adds complexity in managing data.

If the purpose is to simplify, then you would want to remove the components that add complexity, but here instead of removing them, we've simply changed them, and removed some of their useful functionality. Complexity remains but in a different shape.

My criticisms are personal, in that it feels like the page is trying to be willfully deceptive, and that's annoying.
