It's about people who aren't creative themselves (or who don't have a specific creative skill, like drawing), who want to get art without resorting to "paying a human artist to create it."

Honestly, as someone who's worked a lot of boring mindless jobs where at least part of the work could probably be automated...when I think about how you'd do it, "organizing all this info in a way the computer can understand, and then programming a system to process it" would still be a complicated effort that requires a lot of human attention upfront! There's just no path that's really as cheap or easy as people want it to be =(
