Before the Internet and print-on-demand, it was hard for any rando to write a piece of text and get it in front of the eyeballs of strangers. You had to at least commit to spending a chunk of cash on a press run. That meant that the average quality of a randomly selected piece of text was relatively high. Then the web and print-on-demand democratized that. If you read a random web page, or a randomly selected post or comment on some social media site/app, odds are it will be near nonsense. Likewise a randomly selected self-published work. (Though the quality tends to be a bit higher there because the pressure to write a work of a significant enough length tends to filter somewhat.)

You don't notice this as much because you almost never encounter a truly randomly selected text work. You're reading only comments that get upvotes, and blog posts that get reshared, and self-published works with a lot of reviews and sales. Crowdsourced sorting has helped make the giant mass of garbage less visible.

Likewise, before digital cameras and cheap web hosting, it was hard for any rando to take a photo and get it in front of the eyeballs of strangers. You have to pay for film, pay to develop it, pay to make enlargements. That meant most photos you saw where either snapshots with personal relevance that gave them quality, or actually decent photography. Then digital cameras and cheap hosting democratized that. If you look at a randomly selected image posted (and not re-posted) to Instagram, Facebook, Flickr, etc., odds are it will be blurry poorly-lit trash.

Again, you don't notice this because Instagram and company use crowdsourcing, AI, and algorithms to ruthlessly filter out the garbage.

The same story is true for a lot of music coming out these days, though that one still have a few structural gatekeepers in many places.

If AI really does radically lower the bar to shipping, an app, we should expect to see the same thing play out there too. An enormous sea of worthless shovelware with a handful of decent apps mixed in. It will become even more important for app stores to filter and curate these collections so that users can find what they want.
