>> but how does their advertising model work when people expect summarised and accurate information instead of scrolling pages of ads?

1) because that fancy summarised results page will effectively be the ad. The results will push you towards google's partner sites or promote behavior benificial to them.

2) because partners may soon be able to pay to change the results of searches. Who won an election 20 years ago? That "fact" from the AI could depend on which answer has been sponsored by which political interest. What happened in china in 1989 ... how much money do you have?

3) the user becomes the product. No ads in search results, but our searches and online behavior tracked by them will be sold to whoever is most interested in what we do online.
