* It turned out you could do it: I programmed it for the IBM 704.*

Anyone else find this comment motivating? It kind of sums up a moment of reflection I guess I somehow aspire to. Find an insanely difficult challenge, that you deem important enough to devote a significant amount of time and energy to, and then one day: "It turns out you could do it: I programmed it for the ${preferred architecture}." Thanks Doug^H^H^H^H hold on - didn't Steve Russell implement McCarthy's original Lisp on the IBM 704 - not Doug McIlroy. What am I missing that pulled me away from my moment of zen here?
