Theranos wasn't something that failed to happen because of execution or market trends, it was something that mathematically could not and cannot happen, ever. Also, when that became apparent, the company's response was not to pivot to something else, or to close up shop and return their investors' money; instead, it was to fraudulently claim that this mathematically-impossible process existed, and to sell it.
