Problem: Hajji, being the secretive sort he is, gradually learns to hide from your big, sophisticated robot airplanes.
Solution: Make tiny, simple robot airplanes that look like bugs and birds, enabling you to facilitate a meeting with Hajji and his 72 virgins in a quick and efficient manner.
New problem: Cats (and other things):
There are bats, birds and other insects out there that will find it a cinch to catch robot butterfly's, mechanical birds or even cyborg moths. It will be a long time until our artificial flyers will be anywhere near a match for Nature's airbourne hunter-killers.
I can definitely see the disappointment involved in creating a zillion dollar droid which ends up showing you nothing more than what the inside of a cat looks like. And boy wouldn't that be an interesting thing to scoop out of the litterbox?
