Yeah, I raised it because the ACA ruined that grift. If they can detect a “pre-existing condition” in a way that wouldn’t allow people to know they were doing so, then they could potentially discriminate without there being a traceable way to discriminate. Sort of like denying job applicants because their name sounds black without seeing their skin colour.
And the cost might be prohibitive, but not if it’s already built into everyone’s non-deletable facebook app and they’ll sell you the info for ten cents.
Plus I think it personally suits me to be unrealistically dystopian so that when things go well I can say, “well good” and when they go badly I can say, “Look at this amazing prediction!”
