I've not posted a lot this week, but it belies all the research I've been doing. And what I've learned this week is: when billionaires set out to "change the world," it's a form of atonement. Being in the right place at the right time with the right skills doesn't make you humanity's steward. There's no shame in building a more efficient oil pipeline, a great car, or a better OS, and then stepping back. The impulse to do more usually comes from a deeper emptiness. No amount of influence or innovation will fill that. Only God can.
