Sure, computers can do a lot, and what they DO accomplish, they tend to do very fast. But what they accomplish is not "AI". Even Watson is not "intelligence", it is only the illusion of it.
Since we don't have a clear idea how (human) intelligence operates the statement above is pretty vacuous, and likely not at all relevant.
Sure, cars do not "run" in the literal interpretation of the term, but for all practical purposes they are better than humans at "running". If we end up with computers that effectively outperform humans in most "intelligent activities" how they achieve it would be incredibly irrelevant.
