Dear Elon, Today is a hard day. We are all saddened by the tragic death of Joshua Brown. You represent to many of us a heroic ideal - a man who by sheer force of will is changing life for the better for millions of people - changing the course of entire industries while improving the daily lives of consumers like me and doing something good for the planet at the same time. You dedicate your life to this task, you sacrifice your relationships, your time, your body's health in your uncompromising focus on making your dreams a reality. You've put your own personal fortune on the line more than once - a move that many of us with means secretly admire while knowing that we would not be strong or brave enough to have made such risky moves in your shoes. In an era of a United States beaten down in so many ways you represent a return to optimism, to hope that a better future is possible. You embody a one man revival of a forgotten American ideal, an American dream - that people can come to this country and succeed on the highest level if they have the dream, the drive and ability to execute. You are willing to dream dreams bigger than most of us would ever dare to entertain - and the almost superhuman ability to execute on those dreams in the face of unending opposition and hate. There are not many things which get me choked up, but reading the endless parade of shallow, poorly thought out, negative articles about Tesla over the last couple years makes me cringe. You've never seemed like a man who needs the support of those around you - you have an internal fire, drive and ability to tolerate pain which I would pay millions of dollars to possess in my own character. Please don't falter, don't hesitate. Don't lose a step. Don't let off the gas at SpaceX or Tesla. Don't listen to the doubters - lead us on and continue to be an inspiration to America and the rest of the world. Thanks for giving me Autopilot. Thanks for building solar panel factories. Thanks for landing rockets in the ocean. And thanks for inspiring a generation of dreamers yet to be born who will read about you in their history books. Never give up!
