Personally, I believe that at the level of the whole of humanity, this issue can wait until we solve our most deadly problems, which are many, too many. And all this bypassing that what we most desire is to achieve an immortality of our own and exclusive individuality. If you talk to a person about a collective immortality, about a kind of global mind, most of them go back to capsizing, because if they can no longer recognize themselves, if they are no longer "he": What difference would there be with death ... .. if I am not me anymore.
For this techno-optimistic current, we have before us the responsibility to lead the evolutionary process of humanity and radically transform ("improve") the human being through the interaction and implementation in our body and mind of emerging technologies beyond the conditioning and limits imposed by nature, of which we are an inseparable part.
