> I’ve got this suspicion that sans-serif fonts are fashionable because […] As you call it out, it is fashion. Fashion is rarely rational. Designers like what they like and their trends are often based on things like whimsy or "what looks different from last generation's fads". I think there's a likeliness the causality arrow points the other way: designers are deep in a sans-serif fad for a number of weird aesthetic reasons. Designers force "all" the designs to sans-serif fonts. Serif fonts don't get enough love in key places in software interfaces or desktop publishing. Serif fonts start to accidentally accumulate kerning bugs because they need more eyeballs. I don't know for certain if that's the case, but it fits the general Razor when dealing with fashions of any sort. (I don't know if there's a name for this particular Razor like Occam's or Hanlon's. "Never attribute rationality to fashion.")
