It all boils down to whether you believe that activities in space should consist of a series of big grandstanding stunts, or whether you think that space should become just another place where people live and work - expanding human horizons. It seems clear that the sorts of missions upon which Armstrong embarked, though pioneering at the time, were not sustainable. The main reason for this lack of sustainability was that the hardware was bespoke and too expensive, and required too large a ground crew to operate. What we should probably be working towards are sustainable and increasing levels of human activity in space. This means working towards lowering costs and standardising hardware, and greater commercial involvement.
