There's still enormous potential for technology solutions in the healthcare space. The population in every developed country is getting older and sicker. AI can help a little bit with building those solutions but there are no magic bullets: we still need lots of people grinding away on hard problems.
Perhaps this is too US-centric, but as someone who used to work in health fintech, I strongly disagree.
The US healthcare system is well and truly f'd, but I think 98% of these issue are government and society policy issues. If anything, I see so many companies trying to take advantage of the complete dysfunction in the US healthcare system to be yet another middlemen siphoning money from systemwide inefficiencies.
