This isn’t immortality.
Even if every memory and personality could be uploaded into a robot, it would still be a robot, and the person from whom the memory and personality were copied would still be the same person. The robot might last longer, but the person would still die.
I also think that, no matter how well the person’s memories and personality were transferred into the robot, the behavior of the robot version of the person would soon start to deviate from that of the original person. It eventually would not behave much like a human being. That would be an unavoidable consequence of development guided by mechanical programming instead of biological processes.
I think it is a silly experiment myself and will go nowhere. But a lot of scientific experimentation produces knowledge and products useful in other unintended applications. Viagra is one example. It was develop to treat hypertension and angina and is now being used to treat altitude sickness and that other ailment discussed by Bob Dole.;-)
As a Christian, I think the whole idea of non-Salvation-based immortality is a non-starter. Yet, as a science buff, I am fascinated by the work being done to extend life dramatically.
Contrary to what the popular culture thinks, I believe old people have much greater capacity to make a contribution to society than younger people. Wisdom and maturity come with age...and the more age, the better.
As for me, I am in my sixties and feel like I am just getting started.
