I admit I enjoyed the positive or hopeful endings of the stories. Don't be misled by the phrase optimistic sci-fi here the stories are optimistic (in some cases less clear than other) but not "saccharine sweet" there are some good thought-provoking sci-fi short stories here.
Confession, I hadn't come across all the writers in this book before, but I enjoyed all the stories. The range of stories was interesting, including:
- possibility of benign AI in "The Church of Accelerated Redemption" by Gareth L Powell and Aliette de Bodard;
- rise of a developing country "Solnet Ascendency" Lavie Tidhar;
- understanding humanity "Sarging Rasmussen: A Report (by Organic)" by Gord Stellar;
If you like sci-fi short stories, this book is worth a read.
