I attended this talk in person, and have to say it was easily the most entertaining of the series I've seen all year.<p>The most interesting take-away was that DHH wants to build scalable companies in the sense that profits grow non-correlated to the workforce, ie. you don't hire 2 more people for $500million more in profits.  Someone asked, wouldn't it good to employ 100k of people and create 100k jobs to which DHH said, no it's better for my personal wealth (which is the point of all good business) if I keep the profits to the smallest number of people possible - those 100k people should actually go out and make shit instead (his words).  Food for thought.
