Ask HN: Loss of entropy in AI based alt-self chat apps

I have seen a bunch of well funded companies raise money with the thesis they will create alt-self of humans which can chat on behalf of humans. I have tried explaining to a bunch of folks how there is entropy loss in such conversations very much in sync with how averages of averages cause smoothening of any series. All i get to hear is a bunch of gen ai jargon from a bunch of folks who have raised a lot of money because no body understood their jargon and threw money on them. they don't get basic averages and want to build alt-self chats. Genuine rant but wanted to ask HN folks, isn't the loss of entropy very obvious and very explainable
