I was walking my dog a few months ago right after dusk and randomly saw the starlink train, it was a linear constellation marching across the entire sky, from horizon to horizon, and lasted at least 2 minutes.

It was both amazing and disturbing.

The "train" is only visible for a week or two after launch. Once the satellites get to their operational orbits they are not visible. So you'll never see the thousands of satellites that are up there; they can't possibly ruin your view of the night sky.
