@LukeAlmighty it is scary.. maybe the intelligence is not that special as we think.. then the question is, where is the point of consciousness begin.. i guess there is no such a point.. when I look at my cat, she is definitely self-conscious, just the level of it is lower than mine.. maybe it is also not that special.. and it's a question of number of neurons.... on the other hand, elephants have bigger brains with probably more neurons than humans.. it scares me :-)
