If I tell you to write a brilliant piece of music, even if you are a good musician, you cannot do that on command. You can only kind of do it by accident, if you have special talents (and then maybe only once!). But the thing is, the moment you have created it, we can almost all judge wether it is brilliant or not. That is really easy. But to actually create it in the first place is incredibly hard. So if we ever solve this, that also means we should be able to create brilliant art on command?
