There is no better time for manned space exploration than now. Certainly within 100 years and possibly within decades, robots will be better than humans in nearly every aspect of space exploration. I think the proponents of manned space exploration see their window closing, and are getting a bit desperate. If we want NASA's research to have benefits to broader society, it would be best to redirect it all toward robotics and artificial intelligence. This would give the most scientific benefits as well as long-term engineering benefits. Currently, the money being spent on manned space exploration has negligible side benefits. A lot of it is being spent on old technologies, like non-reusable rockets that are too expensive to fly.
