It is stupid. Some things are better then othr in different things.
Currently people are good in generlizations, abstract thinking, spatial coordination, pattern recognition and finding. Computer are better at borring stuff which repeats the same many times, like searching for something on big list, or calculating trylions of formulas by repeativly applying rules.
Things are slowly changing and more and more stuff which was reserved for people can be done by computers, but this doesn't underestimate us in any way. We created this machines, we programmed them, now we have more time for other usefull things, we move humanity to the new future. I really don't see a problem.
I personally always very happy when my own programs can outsmart my or make me supprise :)
Chees or music isn't very hard thing. Actually Deep Blue or this robot achived they results slightly in different manner than we, and I would still say that they failed. Deep Blue was using brute force, not asbtract and general strategy planing, he was not very good at assosciating common patterns and predicting what will happen without simulation. This is what is called inteligence, to predict what will happen without actually simulate or carry experiment. But Deep Blue was performing full scale brute force simulation, so it isn't inteligent. It is soft-AI, Deep Blue, doesn't know about abstract properties of chees.
The same is with music. Maybe this program have rules, maybe it can compose greate music. But this music is created for people, and it isn't human, so he is actually creating music which he can't hear. This is ironic. But he doesn't really feel or know by itself how to create this music. Is it very innovative? Could he create new style in music? Or create new tonic system, could it have good imagination to create new music instrument? Good in the sense that it will be nice to hear such instrument be humans? I don't think so.
It is still soft-AI. All this is fake.
