"Moonbase? Not a current need I think."
Read Roving Mars by Steve Squires and dig up some of his interviews. He often mentions how much more productive a person is over a robot. His Mars rovers would take a day or two to inspect a rock outcropping that a human geologist could examine in minutes with nothing more than eyeballs and a hammer.
Robots are good at dedicated tasks, but they have very little flexibility. If you want to look for certain minerals across a large area, use a robot. If you want to find what is the most interesting thing about that same area, a person will do a better and faster job.
