a return to "craft" might be a response to exactly this phenomena. by actively signaling "effort", some artists differentiate their work from "low-effort-seeming" work - actual effort involved notwithstanding. however, effort need not be viewed as art-legitimizing factor
i think the increasingly pervasive idea that effort is what legitimizes art breaks down when you consider that the best conceptual artists often actively aim to obfuscate how much effort goes into producing theirs
