ETA: Seems this was meant to be a different kind of content warning. Whatever. --- I don't know that specific series, but Greg Egan thinks ideas further than usual in entertainment, usually ends on a note that's neither down nor up, but nondescript and even nihilistic toward normal-human values, like setting yourself into an endless loop of trivial emotional experience of no more than a few seconds content in re. The author often plays with minds like that. Depending on your make-up, you could interpret the described personas as tortured people, or free, or ... whatever. Somewhat Camus-like. Just with hard sci-fi.
