To me, transhumanism is a temporary movement — transitional. Its role is to help individuals and society transition to living in a world where some portion of society technologically transforms their minds and bodies on both incremental and fundamental levels. This might range from getting a Google-connected neural implant to uploading one’s consciousness into a virtual world. We transhumanists consider (cautious!) developments along these lines to be a good thing, and feel that the most pressing objections and concerns have been adequately addressed, including:
Say that the mind were non-physical, metaphysical, or whatever. Still, we know that physical brains give rise to minds, so mass-producing physical brains would still allow us to mass-produce non-physical minds. So, pure reductionism is not even necessary to carry the point I was making in the previous post.
