Meh, Jon Spiro thinks he's all cool and great because he can "outsmart" the great 13 year old Artemis Fowl. He just has a lot of money and a lot of people working for him. I really don't think he is actually that smart. I think he is manipulative and therefor decieves the reader and other characters that he really knows a lot. I think he knows enough about what he does to be able to be pushy and commanding. Apparently he has some sort of brains, it takes some to run that business he has plus he makes a ton of money.
