Still add a little rudeness, selfishness and other ugly human qualities and quite human? You have a distorted concept of a rational person! Rudeness, selfishness and other inhuman qualities are the qualities of “devils from hell”, but not human !!!They're creating software that emulates human behavior...using their own self image. Hence, laziness is not so surprising.
Might as well add some boorishness, selfishness and other nasty human traits and it's perfectly human-like. But much more intelligent.
