Couple of points: The problem with cryonics is biological. Nerds may rave about how this "really cool" (pun intended) new technology will enable us to cheat death but nerds rave about ever imaginef technology as if it is real now. The fact is that away from their algorithms nerds are CHIMPS (acronym - Completely Hopeless In Most Practical Situations) and in their techno - frenzy forget to consider what happens to the cells in complex organisms when after being frozen they are unfrozen. It's not good and there is no way of preventing it without killing the cell first.
Sex robots indistinguishable from real human beings? I've had girlfriends who superficially were indistinguishable from real human being but on closer acquaintance revealed themselves to be monsters.
All in all I'm not scared of technology but after a long career in tech I'm discriminating enough to make informed choices on what I will use. For example the smartphone my son and daughter bought me lies unused in a drawer while I continue to use an ancient burner which does everything I want a cell phone to do. After twenty minutes playing around I recognised the smartphone is really a surveillance device pretending to be several other things.
Camera? Got an excellent digital SLR, music? got a great hi fi, Location monitor? No thanks, I always know where I am, nobody else needs to. And for everything else the old burner works fine.
