The issue is precision. Your finger's touch surface is about 1/4" in
diameter, more or less. The mouse pointer is actually a square (large
enough to display the arrow), whose active area is a few pixels in
diameter. There's no way you can have that kind of precision with your
finger tip.

Far into the future, evolution will be delivering humans with ultra-pointy
fingers.

Just kidding. I'm quite sure science will find a way to make a wireless
interface directly to our brains.
