It's entirely incorrect that the robots will have to work independently for years. To be economical, they would need the ability to be assigned tasks at granularities of hours, down to 20 minutes. If Planetary Resources engineers can get it down to "retrieve material from sector XY" then the entire operation could be controlled from Earth.

The idea of entire space stations, and robots made from Platinum will always sound crazy to my pre-abundance-platinum mind :D

The idea that we would make disposable drink containers out of aluminum would have been crazy in most of the 1800s, when aluminum cost as much as silver.
