Heh, part of the goal of 'simplfying' is so that you can reason about things. Most people don't really conceptualize what it means to have 100 billion dollars of 'cash on hand'.

We can make the numbers more accurate. Hell if Tim Cook hired me and gave me the budget for it we could knock this out in a couple of years. I'm sure there are at least half a dozen folks out there who could. The simple point remains though which is that you can solve this problem with money, and you can make the solution time arbitrarily short by scaling the money.
