"Buddhism is a faith tradition and set of spiritual practices whose core idea is that human beings can become more than human by application of mental technology and self-discipline. As such it is probably the most compatible of the older faiths with transhumanism. But it is also quite challenging for many transhumanists in its insistence that there is no discrete, continuous ego that could be protected and perpetuated. Many of the immortalists, for instance, find that a threatening idea, but I think we will increasingly see the truth of the emptiness of the self as we apply neurotechnologies and life extension."
