This was a very enjoyable listen. I spent a long time after reading Upgrade struggling to decide between this and Recursion. I think I made the right choice, as I am very excited (after a short break) to pick up Recursion.
I only found a couple of passages a tiny bit 'slimy' physics wise (the schrodinger's cat bit comes to mind, would struggle to recall what about it exactly), but they didn't impact my enjoyment of the story.
The narrative itself had me regularly thinking about the possibilities when I wasn't listening.
