I agree that tools can and should be improved, but it's not just a matter of tooling. If you're running 10,000 machines then you divide your management costs across them and treat them as cattle and end up spending (not real numbers, obviously) 0.02 person-days-per-month-per-machine or whatever on managing them. But that doesn't mean that with the same tooling you could run just one machine with just 0.02 person-days-per-month, because a lot of the benefit you're getting from scale is the ability to make one decision and do something to all 10,000 machines at once, and it's the decision that takes time and effort.
