Make default search be a version of ChatGPT and put ads on it? Could work (I wouldn't use it though). The way a lot of people use their browser they might be fine with it if it puts navigation-type links up top (I have literally seen a technical colleague with a PhD do a Google search for "x" and click a link rather than type the ".com"). The inference costs would surely make it hard to profit from though.
