You gave the exact answer I was expecting, but I'm not convinced this suffices. It /IS/ an obsession... my late night coffee binges are the stuff of legend (mostly because I rely entirely on natural stimulants when my other friends take more unorthodox steps to maintain.... "consciousness")... but WHY is this so? My stimulated friends are there for the simple pleasure of being wrecked on particular drugs, does the brain of a hacker/creative entrepreneur expect a similar payout? you mentioned being motivated by money... so by breaking (or taming?) the natural rhythms of sleep, does one invest some abstract personal commodity in the hope of future security? What could motivate this?
[ASIDE: notice that I'm trying to _START A DISCUSSION_.... voters/recent posters would do well to take that into consideration as for some reason it has been overlooked of late]
