Yah I was thinking of Diaspora a bit when I included the word "few" lol. Although even in that case Egan is willing to hand-wave away technology in one place if it is the most narratively convenient way to move the story around to some other technological or philisophical conundrum he's after in particular (like how the computer technology of a Polis is basically just magic) or if it makes the story more accessible to a human audience (like how the "gestalt" sense is usually written as straightforward human-style vision even if it is ostensibly some distant derivative there of). If we do start uploading our brains into computers I don't think I'm going to give Greg Egan credit for "predicting" it, but he did take good advantage of that trope to explore some really cool ideas. IML the point of sci-fi is to ask interesting questions. Very rarely is that question "what is the absolutly most plausible thing that could happen next century?”.
