It's nice to see them trying with advanced robotics and AI, but it will be some time before robots and other automatons reach a level of sophistication where they will replace people entirely, for good. In any case, they will be of great use in assisting us with various tasks and projects. What will be the heyday for robots is when quantum processor driven AI and nanotechnology become widely available and advanced to the point where synthetic neurocircuitry and sensory systems can be grown to spec, for whatever tasks is needed to be performed. This is also where the use of quasicrystalline metamaterials will come to the fore. Given another 10-50 years, and we'll see quite large strides made in these areas, so I don't think the days of R2D2 and C3PO are all that far away...or even the robots out of I-Robot for that matter.
In the meantime, if we don't go back to the Moon for another 20 years or more...and even onto Mars shortly afterwards, then it will be nothing more than a completely lack of political will and financial mismanagement that will prevent us from doing so. That, and an even greater erosion of our collective will to actually strive to become better than we are, than what has already occurred within our society. We have lost the plot...we could be doing so much better than what we are now. We have the capability, now, to do so. It seems we just don't want to, or don't care to do it.
