There is progress being made on the _scientific_ effort to cryopreserve organic materials (ex: https://www.sciencedirect.com/science/article/pii/S001122401500245X https://www.sciencedirect.com/science/article/pii/S001122401...). The argument is not that you will live forever, it's that what we consider "dead" today may not be the same as what's considered dead a hundred years from now. A hundred years ago if you had a heart attack and went unconscious, you were considered dead. We know now that there's a lot of things that can be done to revive someone who has just collapsed from a heart attack, but the awareness wasn't there yet. I'm not interested in cryopreservation personally, but it's quite a stretch to lump the efforts in that space along with astrology or psychic healing.
