I Make AI Models to Sell Real People Clothes

Last spring, the clothing brand Levi Strauss & Co. announced plans to introduce "customized AI-generated models" into its online shopping platforms. These "body-inclusive avatars" would come in a range of sizes, ages, and skin tones and would help Levi's create a more "diverse" lineup in a way the company considered "sustainable." A lot of (real) people were appalled. Why not give those jobs to actual humans of the sizes, ages, and skin tones Levi's sought? Was "sustainable" just PR-speak for "cheaper"?
