I don't know yet how the crypto world could change my life, but people are so convinced to invest 1.5B dollars. Either they are very smart or I'm very stupid.
Theranos was valued at $10B, with somewhere in the region of $1.5B invested. It was also entirely fraudulent, with explanations of their science that made no sense.
The amount being invested does not translate into any bearing on reality.
Being able to hire experts in one field doesn’t make you omni-competent. There’s a long history of famously successful people embarrassing themselves once they get out of their area of expertise, and in this case you’re also talking about someone who is rich enough to run with a whim because he won’t suffer any real consequences if his gamble doesn’t pay off.
Again, history is full of counterexamples. Not everyone who is a rich business owner is especially intelligent but, far more typically, there is a huge difference between being unable to critically consider an idea and unwilling to do so. This can actually be worse for highly-accomplished people if they start believing their own PR and don't have people around who are comfortable challenging them.
