You have read so much on HN about how hard it is for a non-developer to hire a great developer, and how hard it is for an office culture to survive the loss of a great leader. Why do you think any other field is different? How could Stalin dependably hire the world's greatest ag planner if he is not a great ag planner himself, and even if a great planner was chosen, how could he reliably ensure his office remained great after his tenure there?

That's not the only problem, but it's the main practical problem, and a serious one.

Edit: and that's even assuming a qualified person exists to fulfill some of these dreams -- definitely questionable.
