Agreed - even if there's a vastly superior search engine released tomorrow, so many people grew up with Google and learned how to deal with it, it's the default in most browsers - a space owned largely by Google - etc. It's even harder to get a large number of users to move if the product works differently.

I rather think LLMs will ruin the web with insane amounts of garbage content, and with it most of Google's livelihood. Hopefully not by this time next year though.
