Some other people equally foolishly make the opposite claim that AI is progressing so fast that there is a danger that within a few years robots will be taking over and perhaps keeping humans as pets. This fails to take account of the really challenging difficulties in understanding many of the capabilities of humans and other animals that we cannot yet replicate in software systems or robots, for instance the visual and motor control abilities of a squirrel in a tree-top or the language learning capabilities of human toddlers.
