A couple of years ago I posted a little piece on the Kessler Syndrome here (includes a brief discussion one the topic at hand, if you need a reminder), and the bottom line was "yeah, don't worry about it – yet."
Now Kessler and a co-author have recently revisited the topic, and their results are not so sunny. You can read the abstract and download the paper here, or listen to Sabine Hossenfelder's take on the matter here. It's going to be interesting to see this one batted around over the next few years. With such wildly divergent results, there's going to be a good academic catfight.
My advice: Enjoy your Starlink while you can, but brush up on your HF skills too. And if it comes to it, enjoy the light show.
Protip: Never exceed any limit labeled "Runaway Threshold." Don't, just don't.
