If Google had to launch something similar to New Bing to general availability, the cost of search for sure would go up and margins will go down. Is the google organisational hierarchy even setup to handle a hit on search margins? AFAIK search prints money and supports several other loss making products. Even GCP was not turning a profit last I checked.
It does not matter now if ChatGPT is successful with their product. the fact that you can take these LLMs and put them anywhere EXCEPT google.com, Google is f'd up.
The last generation was creating the habit of going to google.com before jumping off to other websites. That era is over.
I rarely go to google.com now. If the LLM is in ChatGPT + Notion + Office 365 + VSC, opening a browser to type to an address bar is silly.
