Explosive! Musk bluntly states: The heart can be replaced. A disruptive technology is coming. Host: What's the most important organ for a person? Musk: It's the brain. Host: Not the heart? Musk: The heart can be replaced, right? Host: Yes, indeed, heart transplants are possible. Musk: Kidney transplants are possible too. Host: I see. Musk: What about the brain? Host: The brain… what's wrong? Musk: If you replaced your brain, who would you become? Host: …Huh? Musk: Where are your memories stored? Host: In the brain, I guess. Musk: And your thoughts? Host: Also in the brain. Musk: And that self-awareness that makes you believe "I am who I am"? Host: …Also in the brain? Musk: That's right. Our very existence is inextricably linked to the brain. Host: I understand now. Musk: There are about 86 billion neurons in the human brain. Host: 86 billion?! Musk: They form a massive number of connections. Host: … Musk: The very act of me speaking is neural activity in the brain. Host: Yes. Musk: Neural activity is converted into sound and transmitted to your ears. Host: So that's the process. Musk: Then, corresponding neural activity occurs in your brain. Host: In other words? Musk: We essentially exchange information through our brains. Host: … Musk: It's just that humanity hasn't fully understood this mechanism yet. Host: That's why Neuralink exists? Musk: Exactly. We are developing technology that allows the brain and computers to connect directly. In 2024, Neuralink completed the first human brain-chip implantation surgery. The goal of this technology is to read brain signals to control devices such as computers. However, reading brain signals and truly understanding human consciousness are two completely different things. You can have your heart replaced, and you'll still be you. But once the brain is replaced, who exactly is this "me"? Thinking about it further, it's truly profound…
