This seems to be that there's just so many degrees of freedom, that there's a pretty reasonable chance on any day that you're in a situation where nobody has been before. Or as PG put it once, my job is to think thoughts nobody has ever had before. That being said, that doesn't mean the majority of the situations you're in are completely novel, just that there's a reasonable chance of at least one occuring.
