In 2018 an obnoxious researcher working at a company known at the time as DeepMind told me (who was working in healthtech) that "AI in healthcare is a solved problem".
It's 2023 now. AI in healthcare is a rounding error and will likely stay that way for a decade or longer. Google blew a 7 year lead of being an AI-first company to a non-profit. DeepMind is now a team within Google, similar to Ads, Drive, and Shopping Express.
