When this is perfected I wonder if a rich old person would be tempted to have a person with the body they want, to be kidnapped and have their own head transplanted on to it to give them a longer life.
Related open question for everyone: Is anyone experimenting with printing cryonically preserved cells? I understand that one of the problems with 3D bioprinting at the moment is that the tissue doesn’t live long enough to survive the printing process, while one of the problems with cryonics is that only very small samples can be frozen fast enough to avoid tissue damage. As I’m no biologist, while these “feel like” they would solve each other’s problems, I don’t trust my intuition.
