Its fascinating how the interest and energy around a project like this manages to be self-reinforcing. The idea on the face of it is quite nonsensical: building a machine to make continuous droning sounds for years at a time. How likely is it that the song actually would play to completion? The fascination is that it is not impossible that the effort will succeed, and its already gone far enough to be quite amazing in the attempt. And in the process its achieved a completely new way to experience music. That last part is both shallow (its a pretty boring way to experience music, and its hard to call it music at that time scale) and deep (with this performance, a chord change is opportunity for ceremony and news releases: its an event!).
