I think this person has too high a view of pre-2021, probably for ego reasons. In fact, their attitude seems very ego driven. AI didn't just occur in 2021. Nobody knows how much text was machine generated prior to 2021, it was much harder if not impossible to detect. If anything, it's probably easier now since people are all using the same ai that use words like delve so much much it becomes obvious.
