What will matter is to see if they seriously tried to address the technical problems or were just collecting investors money. 
Looking at their demo video makes me very skeptical. It&#x27;s basic science that all sound waves including ultrasound carry energy. Producing a voltage into a high impedance and wow&#x27;ing a tech journalist seems very decptive to me. Using basic science to trick the uninformed. [0]
And same with Theranos, it&#x27;s very suspicious that they have published nothing and produced nothing. After years and millions of dollars. 
If someone gets their product 99% done, but the market doesn&#x27;t buy it, thats a business failure. If someone raises millions by lifting a piece of metal with an electromagnet and promises to make maglev cars, that&#x27;s a con job.
The Theranos R&amp;D man also quit and told his wife that none of the techonology worked.  Very bad sign.
