A recent paper came out calculating that it would take two days of lights out at SpaceX headquarters for the whole constellation to shred itself, it was already so reliant on avoidance maneuvers.

SpaceX immediately responded by lowering its target orbits by 70km, the maximum it could legally do without renegotiating formally.

When a high orbit develops Kessler Syndrome, the billions of pieces of debris rain down on lower orbits and cause cascading collisions there, and they keep doing it for centuries.

Not understanding how any of this works, the scientists not being capable of convincing the politicos, or the leaders not being able to escape their local maxima of public stances to recognize a real threat, is a massive, civilizational level hubris. This is pass/fail - the math does not care about our level of understanding or maturity.
