Reframed as "Why would anybody use ChatGPT instead of a search engine for this kind of thing" today? You're correct - ChatGPT is missing some bells and whistles such as real-time data, your location, how many times you've visited the websites of certain restaurants, and so on. However, so do 'search engines' in their base implementation of indexing and ordering links to other websites. I think you'll see some technical limitations (real-time data) overcome and user-focused implementations and features of AI/LLMs emerge over the next year. At that point, I think your initial question becomes more relevant in a general way.
Which is why Bing has the best head start. They have an MVP of combining up to date data from search and the latest in LLMs.
I used it last night on a search that was roughly:
"find the top 10 restaurants in mid-town Manhattan that would be good for brunch with friends that have kids. Include ratings from NY Times and Yelp" Then I further refined with "Revise search to include 5 example entries and a highlight any known specials. Include the estimates walking time from <my location>. Provide a link to a reservations website."
It basically auto-populated a spreadsheet, that I could easily review with my wife. I would need to visit several websites to scrape all the information together in one place.
