In these past 3 years, I've been been able to watch with my own eyes as more and more satellites appear in my night sky. I actually published a scientific paper on satellite pollution: https://iopscience.iop.org/article/10.3847/1538-3881/ac341b
The predictions useful for everybody in the world, but if I'm being honest, my initial motivation was actually to find out how bad it's going to get in my sky. (Turns out I'm at just about the worst latitude in the world for satellite light pollution and re-entry risk. Great.)
