Myeh, they're clearly AI-generated but that's not my complaint here - the absolute inconsistency in style and ultimate lack of 'overall style' or visual grammar's what bugs here. It may as well be a poorly-considered selection of clip art, from multiple disparate sources as used to be a problem back in the 90s.
It'll take a while for people to get used to considering graphic generation as more than mere visual placeholders, I suppose. Early days.
