With respect to Theranos, impossible as in it is physically impossible, because of the non-homogeneity of capillary blood. It simply doesn't matter how good your blood test is, if you are doing a quantitative test, for many types of tests you can simply not get good enough accuracy doing a finger prick test.
The crazy thing is, you don't have to consult biomedical engineers or pore over leading-edge research papers to discover this. You just need to ask almost any med tech with a modicum of experience with blood tests. They will tell you, in no uncertain terms, that Blood Does Not Work That Way.
I will never understand the lack of due diligence performed by the Theranos investors. There couldn't possibly have been any due diligence at all. It's very hard to avoid slipping into victim-blaming mode in any conversation about this company.
> everyone was laughing because back then the batteries density made it impossible for battery to be lightweight enough to be carried in a normal sized car.
That's simply untrue. The issue was always recognized to be economic, not a physical impossibility issue. There were a bunch of (crappy) electric cars in the 90s.
