Because tech people don't understand how healthcare systems work, and reciprocally healthcare workers have neither the education nor the time to understand new tech. The result is what you get today: people from both sides shouting at deaf ears on the internet. Also, the usual corporate culture issues.
One thing tech people absolutely don't understand is how much 2024 medicine is know-how and not science. And that's not for lack of trying to make it science. There are certainly things that could be improved, even through trivial stats. But for the most part, our information retrieval capabilities are so bad that the ability to actually walk the corridors and see the patient IRL is currently not something current state-of-the-art AI can compensate for.
I wasn't referring to marginal gains through the use of AI or automation, I'm referring to re-building everything from scratch so that things are actually efficient and effective. ie, see what Tesla did to the car industry and SpaceX to the space industry. We need something like that for health.
Hot take: If tech people who are used to working with complex systems can't understand it, maybe it's time to replace the whole thing. The healthcare system doesn't make sense at all and is that way because of regulation and a bunch of other crap we need to get rid of/refactor.
