It's pretty silly IMO. Extreme Concept™ isn't difficult to do, and it's even less difficult to imagine.

It's trivial to make extremely long time-based pieces on the web. You load the page, it works out the time/date, and it plays whatever the algorithm says is right for the time date. With the right algo you can make pieces that last for millions of years.

And so on.

There is a sense in which it's an interesting idea, but it's also a cultural dead end. You can only make it bigger and more extreme, and that's more about spectacle than music.
