CS is an interesting personality. On one hand, he writes fiction about the singularity, AI and interstellar travel, and is clearly enthusiastic about them. On the other hand, in his essays he states that humanity will probably never leave the solar system, and that a singularity will likely never happen. Also interesting is that most of his arguments seem to be economic ones. In short, "it doesn't seem useful so the required investments to develop it will never be made". Not so much that it is impossible physically. He might be right, he might be wrong, only time will tell. Personally I don't think it is very useful to make predictions about this (which is kind of the same stance that he takes "it's unwise to live on the assumption that they're coming down the pipeline within my lifetime...").
