I cannot recommend Manna enough (I assume it's similar to the online version [1]). It portrays a version of the future that I believe is achievable by continuing open-source software development and extending it to (more and more powerful) AI.
Manna is an interesting story, but its incredibly poorly written. It starts out great, but the last few chapters feel like they were written by a high school student realizing their deadline is approaching and is still 5 pages short of the minimum requirement.
