Am I the only one who didn't interpret the quote as him showing off? If I used that line, it would be a way of telling them that the problem of segment tuning is an artificial limitation imposed by a format that hasn't gotten enough attention. "I wrote FAT on an airplane" would be my way of saying, "don't come up with better ways to work around my half-assed implementation. spend time improving the implementation so segment tuning isn't even something you have to worry about."
