Good links
Good links. Well worth reading. But seriously, astronomers are clever people and these satellites are point sources of light. Unlike light pollution which is dimmer, but probably next to impossible to mitigate. My bet would be that filtering the satellite tracks out of astronomical images will turn out in the long run to be more of a nuisance than an existential threat to ground based astronomy. It'll presumably take money -- probably quite a lot of it -- to clean the images up. And who better to pay the tab than SpaceX?
