In a world where questions are answered by an engine like ChatGPT instead of people going to ad-filled webpages, Google's business model evaporates. Even if google captures 100% of the new pie, the new pie is much smaller than the current one.
Like, currently a Google competitor like Bing or DuckDuckGo is still sending lots of money to Google because they redirect users to websites showing Google ads. A non-Google ChatGPT pays Google nothing.
Also consider that paying even a dollar a month for a service will result in the addressable market going down orders of magnitude. Apple is pretty much the only company in existence that is able to make people pay so much on luxuries like that.
I doubt Google makes you spend any more money than you were going to spend anyway. Likewise, chatgpt won't make you spend any less. For those times when you want to spend money, Google will continue to serve the purpose of helping you choose which thing to spend it on.
"What are the lowest latency audio interfaces sorted by price" or something to that effect.
Like the person who posted it, that simple answer for chatgpt erases lots of clicks and views and hours of research.
I now query openai find a general idea and then query that in Google.
Speaking in absolutes when you don't have a crystal ball is annoying. And negativity sucks.
