What is the article author trying to point out there? That the artist is a bit dim, I should think.
Certainly. You can tell based on the complete lack of success and following they've had, plus some amateur / shitty work they did in the past.
It’s easy to get stuck in wanting to create but fearing your art will not be as good as what pro artists produce, so you procrastinate on it forever. Folks start dailies (beeple is far from the only one) to force themselves to improve quality through sheer quantity. Other folks follow them to get inspired, and a major component of that is seeing that what a dailies guy makes is, to put it bluntly, not that good and you can picture yourself making something even better.
So, someone posts a daily -> people realize it’s not necessarily so great in absolute terms, but still they comment good things and encourage the artist -> people see that a mediocre work gets positive comments and feel safer creating and publishing something of their own, eventually perpetuating the loop.
As art communities grow, so do follower/like counts, and platform’s algorithms pick up on that and start promoting these to non-artists from the outside who can get mixed up in this mini-bubble: “who’s that with so many followers? I’ll join in, with that number of likes their artwork must be good.”
