Elon Musk has a vision of the future, and — as one of the world’s richest men with four corporations under his reign — the means to try to manifest it. In a conversation with Kara Swisher, he outlines his theory of, well, everything. “I do not think this is actually the end of the world,” say Musk. But at the same time, we need to hurry up. “The longer we take to transition to sustainable energy, the greater the risk we take.” But is relocating to Mars really necessary? Is our species ready to live with chips in our brains? And who’s Musk voting for, anyway?
