That's true misconception about ai. Every person in robotics know
how Rodney Brooks of MIT was able make a walking insect using 8 (or 10)
MC68XX microcontroller in 1989. It is how good your algorithm that
matters.

I think it is the psychology on how we formulate passwords that
should be modelled. Wordlist and its variants is one thing, name of person
related to us is another and so is our favorite funny characters. If we
can model most of these scenarios, the search time would be short.
But there is this one interesting research where instead of using ascii
characters to key in our password, a person picks a sequence of objects
on the screen to authenticate (created by Passlogix). The claim is this
is more secure.
