What is the potential, besides more mail spam and better google search (that isn't owned by google)?

AlphaFold has a shared technical ancestry with LLMs and many people believe that was a truly significant advancement of science that may lead to benefits for humanity and the planet. I don't think this was a one-off fluke, strongly generalizing pattern matchers will be useful in many areas of science even if LLMs turn out to be overblown.
