True of human-made things as well. Most video essays don't get more than a dozen views, most gameplay streams similarly. People playing their guitar and uploading, same. SoundCloud, YouTube, twitch. Human-made app store apps is the same story. Most are not downloaded by even 100 people. Most Github repos don't even get a handful of stars.

I've made songs on Suno that I actually like and have listened to tons of times, not to mention just having fun in general making music, seeing what comes out of the box.

The future is going to be different.

Right now, people effectively spend ~0% of their time entertaining themselves with their own music, art, writing, film, etc.

In the future, it's going to be >0%.

Will it be >10%? Who knows.
