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.."
