AFTER JUST TWO months on Clubhouse, I finally understand how Theranos happened. While articles, books, and films have covered the saga in excellent detail, some of my curiosity lingered: How could we be bamboozled by bullshit of that size and scope? I am curious no longer. After surfing hundreds of rooms on the popular new social media app, I’ve been exposed to dozens of clones of Theranos and Elizabeth Holmes, some of them running companies that have (allegedly) raised tens or millions of dollars.
