Definitely a bit intense, but I agree with the sentiment here. It's a shame that someone (judging by the popularity of his reddit AMAs) so talented at communicating science and technology to the public could be so shortsighted in his view of spaceflight's future. In regards to affordable spaceflight, NASA can't, but perhaps SpaceX and other private companies with brave entrepreneurs at the helm can. It would be nice if Neil DeGrasse Tyson were to meet with Elon Musk and hear his vision of humanity's future in space.
