But you're never going to get the same level of funding for robots that you'd get for a manned mission. Not ever. It's never going to happen. So the comparison is pointless. The only way you'll ever get that level of funding is to send humans, and now and for the foreseeable future, humans are going to be much more capable. Notice I didn't say efficient, because again, efficiency is a moot point. Efficiency only matters if you get the same scale of funding. And that's just never going to the be case. It's pure fantasy to think otherwise.
