I mean most other people who draw, no matter how bad, at least try to improve somehow. Even the most delusional ones will still try different materials, techniques, or ways of rendering things in hopes that something will work better for them.
But Chris has been drawing on a regular basis for well over a decade, and he's barely changed at all. Everything still looks like a 6th grader did it, and he's never moved beyond pencil and Crayola washable markers. It's clear that he just doesn't think he needs to get better.
