There’s no justification given or source cited. You can’t just dig up a paper somebody wrote that agrees with you—you have to actually read the paper to understand what it says and what support it gives to that position.

I see NO support for this position. No reasoning, no primary sources, no secondary sources, not even the personal experiences of the author.

I have not seen any evidence that Frutiger Aero existed before 2017, and 2017 seems like the most likely creation date to me. That’s when it was created, by combining materials from the 2000s in new ways. Call it “bricolage”, perhaps.

Addenda: if you scroll through Google Image search results for Frutiger Aero, you’ll see what looks to me like an obvious lack of actual materials from the 2000s. I see a screenshot of Windows XP, a screenshot of the Nintendo Wii home screen. Maybe a few other random screenshots of apps or web sites. As far as I can tell, Frutiger Aero was invented by taking these few materials and extrapolating a whole aesthetic movements out of it. I see a lot of artwork dated from the 2020s labeled as Frutiger Aero—that’s the true nexus of the aesthetic, Gen Z adults recreating a half-remembered image from their childhoods. Which is fine. It’s just not from 2004. Like how Vaporwave is not actually from the 1990s or 1980s, Vaporwave is from the mid-2010s. I love Vaporwave, but I know that it’s not from the past; it’s a modern remix of elements from the past.
