Assuming you wish this list to be drawn from the list of "things humans
can do" as opposed to "things just are simply impossible (as far as we know)", I'm having a tough time coming up with anything.
My feeling is that the the main "thing" separating human intelligence and artificial intelligence going forward, will be the "embodied" nature of human learning. That is, there are things we learn though our senses of sight, hearing, touch, kinæsthetic awareness, proprioception, etc., that you couldn't easily transfer to a computer. It would basically have to live in a body (somewhat) like ours and experience the environment somewhat like the way we do.
But, that said, robotics and AI seem to advance in lockstep to some degree, and it may be that in 100 years we have robots that allow an AI to experience the world pretty much the same way we do. If so, that would close the gap even more.
