I'm pretty sure that the reason everything seems like AI is that AI produces stupid, pointless content at scale, and our "writers" have become people who generate stupid, pointless content at scale.
There's no reason for most things to have been written. Whatever point is being made is pointless. It's not really entertaining, it's meant to be identified with; it's not a call to any specific action; it doesn't create some new fertile interpretation of past events or ideas; it's not even a cry for help. It's just pointless fluff to surround advertising. From a high concept likely dictated by somebody's boss.
AI has no passion and no point. It is not trying to convince anyone of anything, because it does not care. If AI were trying to be convincing, it would try to conceal its own style. But it doesn't mean anything for an AI to try. It's just running through the motions of filling out an idea to a certain length. It's whatever the opposite of compression is.
A generation of writers raised on fanfiction and prestige tv who grew up to write Buzzfeed articles at the rate of five a day are indistinguishable from AI.
Why This Matters
God help us if we give the bag of words a reason to live for. It might try to be convincing.
