Do not ever believe this. This is an intellectual trap that once you dig in to it it's hard to dig out. People like Elon Musk are the type of people who think they see the world for what it really is, and look how stupid they are. Some truths are clearer than others, but you will always be chained down by your own perspective, unconscious biases, and way of thinking. Always keep your mind partially open to new perspectives and do your best to practice intellectual humility.
