If Google fails to filter out shitty SEO blogs on topic X, how is ChatGPT going to do the same? Changing the results format from a list of links to a paragragh of natural language doesn't alter the content.
Why would the content matter? People Google things because that's all they know how to do, not because the results are amazing. A new way of searching could be novel enough to get people to try, well, a new way of searching.
