I am hoping for brain transplant to become successful. You could switch with someone else and live as a brand new person. We are also printing organs and skin using 3D printers right now. I don't see why we won't be able to change people drastically by reprinting their unique biometrics and replace through surgery. If you don't have your old hand, then your fingerprints becomes useless. You can already order kits to fake biometrics authentication/creation. https://www.theguardian.com/technology/2018/nov/15/fake-fingerprints-can-imitate-real-fingerprints-in-biometric-systems-research https://www.theguardian.com/technology/2018/nov/15/fake-fing... but this is worrying: https://venturebeat.com/2019/10/29/researchers-fool-person-detecting-ai-with-an-adversarial-t-shirt/ https://venturebeat.com/2019/10/29/researchers-fool-person-d...
