Theranos is working on a technology that will exist in the near future, confirmed by many many other companies working on it, so it seems quite likely: <i>someone will succeed in using less blood, to run more tests</i>.<p>That doesn&#x27;t sound like a totally alien idea, and since Theranos will probably not deliver on this promise fully, someone else likely will. However, the uBeam sounds super dubious. I think wireless energy is probably possible, but without a prototype a consumer could feasibly use in their home, and the large amount if scientists I coming out against this a few years ago doesn&#x27;t seem to have shrunk.<p>So, yes it is a really hard interesting problem, but all the fun ones are. I wouldn&#x27;t have invested with the expectation of success, but that the technology developed could be used for something else&#x2F;is valuable.
