2%? You have an interesting idea of the world's population. Just think about what that means. It means 2 out of 100 people can hack into Facebook's Legal Department Admin Panel.

I mean if we are talking "mentally capable to achieve that within a decade if the person does nothing else but strive to that goal"... Perhaps.

If we are talking "sit down right now and do it", then it's more like what... 10,000-100,000 people on earth? Which makes for more like 0.0014%?
