I already know the answer to this, but did you read the article? Ned addresses your concerns.

No, he doesn't. He doesn't discuss the gigantic dividing line between the two different types of systems I categorize above. He also doesn't cover the "feel it in your bones" required in the type 1 systems. Spend a minute reading or listening to Jeff Dean talk, and you'll see what is required to build those types of systems. Spend some time somewhere working on those systems and you'll come across some folks who just have this ready to go and can apply it and the drop of a hat.
