There are not 4000 satellites in orbit, there were 4000 thousand launched, but only about 2000 are still in orbit, and if you take the time to learn, you should rarely have to wait more then about fifteen minutes to see one. Musk alone wants to add 30,000 more. Just to help with your maths, that is 15 times then the total already there, so you should be able to see one *every* *single* *minute!*. If you use any sort of light magnification, for example a telescope or a long exposure, then everywhere you look in the sky there will be a lump of Elon Musks junk. And exactly who is this going to benefit?
