"No, the problem is that unless you specifically tell it what to look for (i.e. an algorithm that can identify four legs meeting a seat at right-angles, etc.) "
And, of course, there is just so much more to a chair than that. Just look at some of the really weird designs for chairs, especially some of the concept stuff from the 60's.

I've certainly seen one that this AI would probably, with high confidence, class as a banana rather than a chair
