I feel that AI does have individual taste (and even "personality"), but it's the same monotonous individual taste across all instances of the same trained AI. The sheer scale of its repetition turns it into a hated trope: like how we can immediately identify slop writing, diagrams, websites, etc.

I'm sure we've all met someone who has a unique speaking style and might repeat phrases or words unusually often, but that still doesn't bug us as much as "the honest truth.." or "load-bearing.."

it must be what TV was like in the 60s. only a few channels. everyone had the same jokes the next day in school or work. We all saw the same episodes.

In this way each time ChatGPT or Claude is released, new memetic phrasology is emitted into the human psyche at astoundind speed.
