We Are Legion (We Are Bob) by Dennis E. Taylor (2017)
This is a very positive book. Bob is an uploaded mind who has to save humanity from itself. He is launched into space and needs to fend for himself. Lots of introspection and interesting ideas; what happens if you can replicate yourself at will? What names will you call all your replicated copies?
A book that doesn’t take itself too seriously, and is a really fun read. Also the first book in a 4-part series.
