Has Elon, peace upon him, done the economics of 12,000 LEO satellites? These things have a life of less than 5 years, which means that SpaceX will need to be launching more than 2400 satellites a year or about 6 to 7 per day, regardless of the weather.
With grasp of manufacturing and logistics that Elon, peace upon him, has demonstrated to date, would SpaceX be able to manage this?
Also, what impact will 12,000 LEOSATs have on other activities worth pursuing, such as Visual Astronomy? Or those of us to go on walkabout in the desert be far away from this sort of thing.
