I really don't see a bright future for search engines. LLMs have exposed a new way to interact with knowledge, which is that, instead of sifting through results/webpages manually, they do that for us and present answers instead.

Sure, they have a ways to go (for example, i think they should provide confidence level for their answers based on how many docs/pages they ran into during training that support a particular answer; show references when asked etc) but the search engine as an interface is obsolete at this point.
