I'm sure SOMA was mind-blowing to the normies whose first exposure to brain-uploading was there, but it is simply pedestrian after reading a high-level transhumanist.

SOMA acts like "hurr, when you are an upload you can be copied just like any other software and that means there can be TWO OF YOU AT ONCE! ISN'T THAT MINDBLOWING?!?!" is an interesting idea. Greg Egan deals with a society where uploaded humans are normal and the implications (space travel is done by beaming your brain-scan to another star and reassembling you on-site, people keep a dozen or more backups of themselves in different star systems, if you find yourself in an irrecoverable situation you send back a final copy of yourself and resign yourself to "local death", which is not considered a big deal because it is just losing a few minutes of subjective experience which we all do sometimes), etc. Robin Hanson deals with the economic implications of a society of trillions of uploads (e.g. em-clans, Malthusianism, running uploads at different speed, creating bespoke copies for a single job and deleting them right after, etc.).

Where can I find a hard science-fiction game that does justice to the idea?
