It's an infinite crap generator, which I can see why people are so enamored with it. Because people seem to want a seeming variety of generic junk almost instinctually. Just take a look at the variety of garbage available on all streaming platforms right now, the variety of garbage on YouTube, or even worse a single aisle in any grocery store: shelves full of crap that's often the same thing with different labels, substances that are utter shit on almost a molecular level but seem appealing or better than others based upon packaging.

Edit: Amazon is nearly a perfection of the instant, endless crap business model. Just imagine when someone hooks up one of these things to a 3d printer. You can then have infinite crap generated entirely based upon your search queries. Now if you'll excuse me I have a patent application to file....
