Welcome to the dystopian future where no human anywhere on Earth can look up and see an authentic sky, as their ancestors did.

And thanks to SpaceX (and now Amazon), astronomers will now have to do their observations from space. If only there was a way to get telescopes up there. Oh, wait... SpaceX just happens to have a way to solve the problem it created!

Should anybody be putting satellites up without some credible plan for decommissioning them from the atmosphere?

If this is anything like SpaceX's constellation, the plan is that the orbits will naturally decay in < 10 years and they will burn up in the atmosphere upon re-entry.

Decommissioning plans are part and parcel of any satellite launch. These small ones will deorbit pretty rapidly if they are told to do so and a bit slower if it happens uncommanded once they are unable to maintain altitude.

At what point should we start worrying about Kessler Syndrome?

> The Kessler syndrome (also called the Kessler effect,[1][2] collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions.[3] One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.[3]
