I wasn’t aware that Adobe had podcasts. In this episode, they discuss how modern design leads to “sameness.”

I listened to the episode (there is a player on the site, no download required), and this isn’t something that originated in modern design. I feel like since the earliest days of art, people have copied success, often to the point where it becomes a trend… and later a dead trend… and later still, a revival. I feel like sameness can define an era.
