This response just never feels true to me. Many of the most successful web comics are crude drawings of just stick figures and text[1] with potentially a little color thrown in[2] and like half of the videos I see on TikTok are just a person talking into the forward facing camera of their phone. The barrier to entry in the pre-AI world isn't actually that high if you have something interesting to say. So when I see this argument about lowering the barrier to entry, I can't stop myself from thinking that maybe the problem is that these people have nothing interesting to say, but no one can admit that to themselves so they must blame it on the production values of their content which surely will be improved by AI.
