People are anything but slow and fragile, at least in 1 sense of the word, in comparison with computers of today. Modern computer models which are typically viewed as the edge of computational intelligence are very susceptible to getting tricked into incomplete models by their input data. Human beings process unfathomable number of stimuli everyday and get placed in unknown situations on a daily basis and very few break down, where as almost all current computer models break down very quickly when viewing previously unseen patterns.
