Slightly off topic for this post, but since it is mentioned here: there is one part of that link which may appear slightly misleading without context. A twitter feed is mentioned, which ended up consisting of posts such as "and then God said", followed by some gibberish. This is actually a reference to a feature in one of his programs (a game I think) which allows one to "talk to God". When you press the button, it simply randomly spits out words. On Reddit, the author asks people repeatedly to tell him what God said to them. He's referring to this feature in his OS and obviously finds entertainment in hearing what words his program came up with for other people. This is reminiscent of fortune cookies. Strange behaviour perhaps, but not so nonsensical when placed in its context. As other people have pointed out, illness or not, this guy has managed to succeed at something highly nontrivial which most people will never do, at the pinnacle of Maslow's hierarchy of needs, namely "Pursue inner talent; creativity; fulfillment". And whether or not some of his writings may be unintelligible, his code certainly passes a strict syntactic check. I mention this here because I have met individuals with the same illness who have not managed to achieve even the bottom level of Maslow's pyramid. So it really is a credit to him that he has achieved so highly despite his illness.
