A bit of commentary on the discussion between Mike Perry and Epstein: once more the issue may turn out to be matters of definition rather than fundamental issues. If we are going to modify ourselves then the issue of just how becomes prominent. A little thought suggests to me that (other than changes to live in a quite different enviroment, such as the planet Jupiter or an asteroid) our physical shape may not change much. However the problem of accessing more and more memory may cause some brain changes; whether those changes require changes of materials isn't clear. But clearly we won't want to carry ALL our memories around with us ALL THE TIME. So we might choose to have many different memories, to be used when we need them. This is likely to need some changes in our brain anatomy, though many brain features would remain the same and we most certainly do not want to turn ourselves into computers in the present sense of the word "computer". In terms of physical modifications ie. increases in the number of limbs, etc, I would suggest that the variety of changes is so great and the variety of cases in which individual changes become more useful than our current bodies runs into the same problem: sure, 4 arms can be useful in some situations, but it can also become a burden in others. We have so far dealt that that problem by TOOLS: detachable parts which give us those features when we want them and allow us to put them aside when we DON'T want them. I see no reason why such a system cannot continue, and remain superior to actual physical modifications. Yes, our tools might connect more with our brains, but they will remain tools. It's not even clear that we'll need more brain connections than those given us already by our hands. In one sense my suggestion about how we might modify our brains can be seen as just as extension of the use of tools. Now they are intellectual tools, but even that isn't totally unprecedented even now. But we may well want to modify ourselves so that we can use our brain with such intellectual tools much better than we can now. Question to Mike Perry and to Louis Epstein: would someone modified as I have just describe become nonhuman, or not? Imagine that we can do all this with biochemistry, and the materials remain those of human beings, though the design does not. Does this make such a person more or less human? Best wishes and long long life for all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=16400
