Theranos was famously founded on pitches about blood testing from finger pricks that literally any phlebotomist and many people with a modest life science background could've told you were physically and statistically impossible on their face. You should be considerably less credulous toward startup grifters.

The reason why you (and everyone else) knows about Theranos is that it was unique, which serves as a bad signifier if you want to judge what is likely to happen with the next startup. Being in prison and losing billions of dollars is just not something most people get excited about.

The reason we know about Theranos is that it ended up in court. Plenty of other startups have had obviously impractical ideas that didn't go anywhere.

The reason we know about Theranos is because they took the grift up to a huge level and went from grift to outright fraud once they had to show actual results.

It is not only not unique, but in fact extremely common for startups to be grifts around impossible technical promises, live a few years off gullible investors who have way more money than sens and/or for whom losing a few million dollars on a long shot is just as bad as me wasting a few dollars on a gizmo off Temu I know probably won't work, and which then die out because their ideas obviously couldn't work.

They even sometimes find a niche by pivoting to some vaguely related tech. Say, while flying taxis obviously won't work, a startup trying to build them might find itself developing into a small company building helicopter propeller blades for some specific niche.
