I’m really put off by the “currently-empty galaxy” claim that comes right at the beginning of the piece. How would the author know? We’ve only sent two probes outside our own solar system, and they haven’t even reached another star yet. I don’t consider it a good sign that there’s a massive unwarranted assumption sitting at the very beginning of the piece. That’s why I can’t be bothered to read further.

I’m not sure what publication this was in, but the claim seems to be supported here: https://arxiv.org/pdf/1806.02404.pdf.
