echelon, it doesn't really sound like you understand the underlying mechanisms of how the human body works. Without a brain, running an entire body would Require a replacement to that brain, so what you are suggesting is unlikely to be very useful. Rather, we are already creating scaffolding for individual organs, and we already have technologies that continue to develop that allow us to test against actual human tissues, such that the end-game you point to of 'in situ' testing already is and will continue to be accomplished. Rather than wasting time and energy attempting to clone an entire human (with all the potential ethical and moral considerations), it is Far easier to simply clone organs, which then allows for direct build/replace scenarios on an 'as needed' basis, And with the full agreement of the source/destination. Further, as we learn more and more about all the detailed methods and ways that various subsystems, grow, develop, operate, and interact, we can simply create more and more detailed simulations of Any human (or any other creature for that matter) to distinguish proper vs improper function, and investigate and even optimize potential solutions Far more quickly and effectively than spending precious time and other resources. That is why computational capabilities are and will likely remain our focus moving forward, rather than the arguably cruder and generally Much slower approach which you outlined. For reference, given the incredibly complex and integrated nature of almost Any living creature, a body without a brain or even without a fully functioning And developed brain would (especially in creatures as complex as humans), in addition to the issues that I already outlined above (along with those raised by others), Also tend to respond Far differently to a fully functional human, thus being of rather limited utility, regardless. |
