People with Aphantasia [1] can have less vivid autobiographical memories [2], so for them it might make sense to make more photos. As usual, this "advice" is rather condescending: I'm a professional photographer and even my photos "weren't worth it" (per the article), so why do you, person of common talent who takes too many photos anyway, even bother?
