Is that any different than media before the internet consumed it all? Media consisted of a couple of news stations, a couple of TV stations and that was mostly it.
I'm also not sure that the recent broadening of media has been a net benefit to society. Look at the degree of polarization in recent years. At a certain point heterogeneity is no longer a societal good.
No, you're correct, media is also a homogenizing force. Regional accents have disappeared, for example. But I would argue that even the political polarization is homogenization, not evidence of heterogeneity, because the variety of the middle was eliminated, leaving the consolidated extremes.
My point is that personal llms will be an even greater force along this same line.
