Search engines were never a user friendly app to begin with. You had to know how to search well to get comprehensive answers, and the average person is not that scrupulous. Google’s product is inferior, believe it or not. There will be nothing normal about seeing a list of search results pretty soon, so Google literally has a legacy app out in the wild as far as facts are concerned.
So imagine that, Google would have to remove Search as they know it (remove their core business) and standup a app that looks the same as all the new apps.
People might like one AI persona more than others, which means people will seek out all types of new apps. LLMs is the worst thing that could have ever happened to Google quite frankly.
