He was my childhood hero, still remains a big influence in all I do to this day. Growing up I always wanted to be a "universal genius" like Da Vinci, so I tried to pick up on science, music, art and pretty much anything I could get my hands on. I think my admiration of his abilities and the realization that he was just a man (like you or I) provided a lot of the drive and ambition I now have. This does have the unfortunate consequence of producing a 'jack of all trades, master of none' type persona, or at least it did for me.

So yes, it would have been amazing to hear him speak. =)
