Further, as someone that has spent far too much time and money trying to find the root cause of a particular issue (with absurdly frustrating inefficiencies in terms of being bounced around, insurance nonsense, etc), I am generally in favor of improving our ability to find a lot of information in a manner like this. Doctors are generally good at finding very common issues they see all the time, much worse at anything uncommon. This can be a real problem. I think it could help the world a lot if we had something like this to improve our understanding of more outlier cases, we might find a lot of issues that were hard to catch without that scale of information. I also think preemptive scanning would catch a lot of issues that go otherwise unnoticed for much longer than they should go, something that also happened to me, but is mostly an issue of systemic inefficiencies in our current healthcare system rather than something that this technology is required to solve. In my case, doing some simple checks that they felt weren't necessary because I seemed healthy would've caught it much earlier.
