The term AI, when used by laymen, is a blanket term for the generative AI and LLMs that big tech is shoving down all our throats right now, not the highly specialized AIs used in medicine. So bringing up the COVID vaccine is largely a non-sequitur.
The rest of your comment is so full of false equivalencies that I’m not even gonna touch it.
Trying to compare the intelligence of a specialized, single purpose AI to an LLM is asinine, and shows you don’t really know what you’re talking about. Just like how it’s asinine to equate a technology that pervades every facet of our lives, personal and professional, without our consent or control, to cars and guns.
