Awesome quote at about 62 minutes: "...This is all getting boring right? The point of this is: invention is boring. Invention is not a great intellectual breakthrough. Invention is not exciting reconceptualization. It's doing all of these hard little things."

A bit sobering for us folks who think Haskell/Clojure/Insert-high-level-language-here is going to change the world. Not that these tools aren't valuable, as they increase productivity (which is kind of a big deal when good engineers cost $100k a year), but on the flip side, it was then as true then as it is true now that you just had to do the grunt work of experimenting with your product.
