The point is you have a very small and closed view of the world. You latch onto small points trying to justify it instead of opening your mind to the possibilities.
Things change over time far beyond what people can imagine. Think about it this way. When I was 13 my favorite show was Star Trek. I loved all the amazing technology predicted for centuries in the future. One generation later, some of the futuristic technology used in Star Trek has already been surpassed by the iPhone in my 13 year old son’s pocket. That technology was inconceivable one generation ago. Things change. Open your eyes and your mind.
