Did Altered Carbon have anything new with technological advancements leading to immortality? When I read the books I was struck by Quellcrist Falconer's approach to guerilla warfare. She thought that immortality allowed guerillas to use time as cover, the way guerillas of past ages had concealed themselves in urban crowds or the remote countryside. It was the first time I had encountered that idea. (Someone who's read even more SF than me may cite earlier antecedents.) The TV adaptation replaced this interesting character and her ideas with the well-worn Noble Reactionary telling us that Technology Is Bad.
