While there appear to be certain modifications already, or soon to come to help the disabled, or enhance your average person, anything really "sci-fi" is beyond our reach and our reach is growing shorter with declining IQs. Won't be much of an issue. Feel bad for anyone reliant on something equivalent to a pacemaker or whatever, to keep functioning properly, some implant or whatever. Because if society goes the people who could service you will be few and far between, as will the resources be. Not a wise investment. Not sure what kind of tech is even available now anymore. Used to look at this stuff decades ago, people used to be into like freezing people until a point they could be revived and cured. That never came to fruition and won't. Transferring your consciousness and not just copying it, won't either etc. Dead end.
