I seriously doubt that we'll see that much on the far side of the moon over the next 80 years. We are now 50 years past Apollo and we have hardly any real presence on the moon, absolutely none for observations looking away from the moon. There are also serious dust & power issues that need to be resolved regarding lunar observations. JWST is basically proof that we are reaching the limit of the complexity of what we can launch without the ability to have human servicing (i.e. what was done for Hubble until 2009).
I would really hate to see us be so cavelier in giving away so easily something that would be so difficult to reclaim. Hopefully, the darkening procedures that SpaceX is going to use will help. But, the higher up they push those satellites into orbit the later at night they are visible.
So count me as a pessimist about this one.
Clear skies, Dale.

I saw my first Starlink cluster pass over last night. Took me by surprise for moment.
Not quite dark, out in back getting a last look at Venus, when I noticed two satellites about 2 degrees apart but moving together, going from WSW to NE. They faded out quickly once in earth's shadow, but then there was another about five degrees behind them. Then another, then two more, then another- and another- and another! None were brighter than about 2nd magnitude but it was quite the parade for five minutes or so. I have seen smaller satellite "constellations" before, typically military
