This is a very well trodden argument the poster is largely right about. But like others who have written about it like Nicholas Carr and Anil Dash, I agree with the concern, but it places a lot of agency on the technology and not the users decisions. On one hand, you can argue for a long time Google was the default page for the internet so you had no choice but to use it to search, on the other hand, people need to use their brains more when thinking critically. They need to learn how to use it to assist in thought. Yes, Google search results are ads, but scroll past the first few pages and dig. Also, refine searches and look at other sources by people you trust. Ultimately, this is a real concern, and I'm glad the author is updating thoughts on it.
