I saw one once and my immediate thought was that I hope such an aberration of my natural view of the sky doesn't become common. I would describe it as eery.
The thought that would be necessary just to see the night sky depresses me beyond belief.
"We in the city can no longer see the night sky, so it's now an unimportant issue."
SpaceX sky-litter is the first time that i've had my night-sky obstructed far-far off-coast on the ocean; that feels significant somehow.
