AI has obvious limitations by its inability to perform some simple tasks even kids can do. It falls down on the job when asked to do things like distinguish a small pointy-eared dog from a cat, realize that a three-dimensional drawing is supposed to represent a three-dimensional object, or recognize human faces. According to Urban, distinguished computer scientist Donald Knuth summed it up well: “‘AI has by now succeeded in doing essentially everything that requires ‘thinking’ but has failed to do most of what people and animals do ‘without thinking.’”
