I've found his writing about money to be distorted. For another example, see <a href="http://blog.samaltman.com/uber-vs-car-ownership" rel="nofollow">http://blog.samaltman.com/uber-vs-car-ownership</a> . Not exactly wrong, but always off by significant factors. (Imagine having a concrete pricing conversation!) Maybe a consequence of living on funny money since a ~teen? The advice rings right, just... distorted.
