Dear Dr. Lawler:
Our literary crawlers have made me aware that your current posts on the subject of

seem to be a good fit for our Doomsday Bookshelf series of scientistic fiction books. I would love to read a book proposal from you, and our AI will merge and publish your posts as a fine contribution to the horror humor genre.

My colleagues and I wrote a bit about using the atmosphere as a satellite crematorium here, and it's bad: https://theconversation.com/a-new-space-race-could-turn-our-atmosphere-into-a-crematorium-for-satellites-276366

There is a group called Lonestar Data Holdings that claims to offer "orbital data centers", by which they mean that they once paid to have an extra drive bolted on the side of a spacecraft used for something else.

But that is not what the current flood of "data centers in space" scams is about.
