> All Google needs to do is launch a superior LLM API on Google Cloud and essentially hedge their bets that any replacement for Google Search will be built on their API anyway.

That would still mean a huge disruption to their core business.

> The other question is how does something like ChatGPT monetize to pay for the massive costs to serve queries? Google engineers have already tested this and say that LLM queries are orders of magnitude more expensive to serve than current results and I don't seen any paid service replacing a free search engine

GPT costs cents, I'd happily pay that. I'm looking at how best to use the newer models personally as it's so cheap.
