In my opinion, if I had to choose from the vast panel of what escapes computation in artistic performance, I’d say experience. Experience of the performer but also the experience of the audience. Through experience, the performer will develop a proper style and will create a performance different from that of someone else. In the same way, someone who looks at the performance will look at this performance through the prism of his own experience. Even a self learning machine may itself have a different experience from ours. Paradoxically, the fact of learning, will prevent the machine to quantify or compute experience. Because that would be subject to his own interpretation.
