There are of course a lot of pluses and minuses to essentially becoming immortal (how threads evolve, huh?)
the most important in some ways of which is the question of boredom as the years, centuries, millennia pass. HG Wells already tackled that in one form in the book "The time machine", where Man was so lazy and had everything done for him in the future that he basically became a slave to the tougher races that evolved along different lines. Star Trek of course built on this idea, but the central warning is that without anything to challenge or stimulate us, we may just bore ourselves out of existence.
There is of course, the "Vampire theory", where you get to see everything, do everything there is over the course of hundreds or even thousands of years, but again bordeom is likely to set in. Perhaps if we could manage to project our consciousnesses out into space and explore the galaxy without need of our bodies, but again, I don't know. Immortality definitely has its drawbacks.
But then, using these robot body things, certain fears and dangers are eliminated: no hunger (one would assume) no death, no disease (other than maybe rust!) and you would also hope no prejudice, though don't bet on it. Mind you, it would seem implicit that there would be no procreation and perhaps either no sex drive or unbridled sex, depending on how things worked out, so in my case I'd say the jury is spending a few more years in that hotel before coming to a verdict.
Must look for that doc, PAN, seems like it would be very interesting...
