Very true about Theranos, but in that case they hadn't even revealed how the technology worked, and the claims they made implied not only a novel core technology but some kind of discovery in physics/science as well, by someone without a formal science background who couldn't explain the science behind her technology. How do you measure something that occurs once per million unless you collect at least a million samples? Most people who understand basic science knew that company had a high chance of being fake. And if I recall properly, most of their investors were from the conventional startup industry, not biotech, and they thought they could play house in biotech without understanding what they were investing in. I would be inclined to believe the same of MagicLeap but in their case the science is already well understood and has been done in an analog form for a long time, using techniques similar to conventional off-axis holography.
