Internet art isn't disposable?

We have over 35 years of Internet art at this point. Can you point me to the non-disposable art?

As for "engagement", we have endless statistics on how long people spend looking at Internet things, and your median viewer is spending literally a few tens of seconds on them.

By contrast, go to almost any movie or concert, and you see that the great majority of the audience stays for the whole 90 or so minutes.
