Some computers currently have the, "ability to learn," or at least have been programmed to analyze a situation and learn from it. Even a Rumba vacuum robot, "learns," the area it needs to vaccum over time through trial and error. By some definitions that's faster, "learning," than even an infant can process. Part of the problem IMO about defning "intelligence," related to machines is what qualtative metrics do you use? By some people's definition the ability to beat a jepoardy grand champion at the game makes the machine very, "intelligent." By other people's definition it's simply that computers like Watson are able to store and prcess vast amounts of data and recall it more efficiently and faster than humans can - hence they aren't intelligent per se. Also, computers are without an argument much better at solvling complex math problems than virtually any human can. Most philosophers believe the yard stick created by Descartes of, "I think therefore I am," or self awareness is the real litmus test to, "intelligence," or lack there of. No computer obviously as of yet is self aware and there is considerable debate to as if they ever will be.
