I guess it depends on scope. I'm imaging scientific or education. Ie things we probably shouldn't have relied on Blogs to facilitate, yet we did. For looking up some random "how do i build a widget?", yea AI will probably make it worse. For now. Then it'll massively improve to the point that it's not even worth asking how to build the widget.
The larger "scientific or education" is what i'm concerned about, and i think we'll need a new paradigm to validate. We've been getting attacked on this front for 12+ years, AI is only bringing this to light imo.
Trust will have to be earned and verified in this word-soup world. I just hope we find a way.
Some of the bigger issues you're raising I think have less to do with technology and more to do with how our economic system is currently structured. AI will be a tremendous accelerant, but are we sure we know where we're going?
This has nearly always been true. "Manufacturing consent" is way older than any digital technology.
