We won't give up the night sky. Starlink won't be very high so majority of satellites will be in the shadow except close to sunrise/sunset.

Starlink satellites are quite small and probably won't be very visible even when deployed. SpaceX is working to reduce "glare" so this will probably be further improved.

Even with a full grid deployed, I doubt you would see more than a dozen satellites at any given time. Someone probably has numbers so please correct me or chip in.
