This sounds like an Alan Kay quote. He meant that in regards to
useful inventions. AI-generated spam just decreases the quality.
We'd need a real alternative to this garbage from Google but all
the other search engines are also bad. And their UI is also
horrible - not as bad as Google, but also bad. Qwant just tries
to copy/paste Google for instance (though interestingly enough,
sometimes it has better results than Google - but also fewer in
general, even ignornig false positive results).
Deep Research reports I think are above average internet quality, they collect hundreds of sources, synthesize and contrast them & provide backlinks. Almost like a generative wikipedia.
I think all we can expect from internet information is a good description of the distribution of materials out there, not truth. This is totally within the capabilities of LLMs. For additional confidence run 3 reports on different models.
