A very large prime number can be sold for quite a bit of money in today's economy, and I think that it's interesting that something as mathematical as that has changed from being a tool for a war effort to something that is currently exploited for profit. You can see this difference in L. Waterhouse and R. Waterhouse's motives. Randy call the hacking a game and even "romantic." If something as pure as mathematics ends up being exploited for economic gain, what's next?
