Tildes Book Club discussion - Project Hail Mary by Andy Weir

This is the fourth of an ongoing series of book discussions here on Tildes. We are discussing Project Hail Mary. Our next book will be Ocean at the End of the Lane around the end of July.

I don't have a particular format in mind for this discussion, but I will post some prompts and questions as comments to get things started. You're not obligated to respond to them or vote on them though. So feel free to make your own top-level comment for whatever you wish to discuss, questions you have of others, or even just to post a review of the book you have written yourself.

For latecomers, don't worry if you didn't read the book in time for this Discussion topic. You can always join in once you finish it. Tildes Activity sort, and "Collapse old comments" feature should keep the topic going for as long as people are still replying.
And for anyone uninterested in this topic please use the Ignore Topic feature on this so it doesn't keep popping up in your Activity sort, since it's likely to keep doing that while I set this discussion up, and once people start joining in.
