Jocko Willink: Hi, I’m Jocko Willink. I’m retired from the military and just wrote a book called "Discipline Equals Freedom: Field Manual."

They have the technology. It may not be perfect, but it doesn’t have to be perfect for them to do some real damage. So it’s something we have to be very cautious of — we have to pay attention to. And we need to be careful.
