I'm no fan of Elon Mask as a person but I give him lots of credit for pushing the automotive and space industries into a new exciting era of innovation and competitiveness. I'm a mechanical engineer in the space industry and I saw first hand as SpaceX broke barriers and challenged the bloated status quo of the traditional space companies. SpaceX has literally influenced and inspired new rocket companies to be born who are further pushing the technological boundaries. On the other side you have a career politician who just loves high taxes. Perhaps Senator Warren should spend more time doing her job instead of tweeting.
