It is particularly bad for a satellite in geostationary orbit to break up or fail. Satellites are packed as tightly as possible into that orbit due to its economic importance (it's very useful for a satellite, particularly communications satellites, to always be over the same part of the Earth), so there is a higher than normal likelihood that this could be seriously disruptive.

- "Satellites are packed as tightly as possible into that orbit due to its economic importance"

Note that that's in the sense of angular separation, as viewed from the ground. They're physically hundreds of kilometers apart.

edit: (Geostationary orbits are ~42,000 km from the Earth center-of-mass; each degree of angle is an arc of ~700 km).

> They're physically hundreds of kilometers apart.

That’s pretty close when your neighbor just exploded and there’s almost exactly zero air resistance to prevent debris from reaching you.

Nah, do the math.

It still is a 1/1,000,000,000 chance, maybe less.

If you want to dismiss an argument, maybe do the math instead of saying "do the math" dismissively and inventing an arbitrary number without even saying across how much time that estimate is supposed to be (one in a billion, what, instantaneously? In the first hour?)

>to prevent debris from reaching you

I assumed basic reading comprehension, my bad.

Also, I don't play by your rules but keep trying.

It's kind of expected here if you are going to call out someone's math to give the process you arrived to yours. Not so much a rule but expected courtesy :) "the solution is left as an exercise to the reader" is not very helpful to an argument.
