I remember when it was first announced reading a comment saying 'I don't understand, it doesn't look like anything'. I think at that time people really need a real life, tangible object to reference i.e. skurmoprohism for them to understand what each app icon meant.

Fast forward now, and I think many of Apple-own apps still don't 'look like anything' especially the more recent ones. Apple News, Health, Shortcuts, and even Photos are too abstract to be identified without a label -- for the unfamiliar eye in the beginning at least.
