Randall Parker comments on Aubrey de Grey's latest paper over at FuturePundit. "Aubrey thinks many biogerontologists entered the field when there was little hope of ever stopping or reversing aging. Therefore most entered to satisfy their curiosity rather than to achieve goals which have practical uses. ... But we no longer live in that era when rejuvenation was absolutely out of the question. ... [new technologies] allow increasingly precise and cheap manipulation of biological systems down at the scale of cells and molecules. Computers allow automation and scaling of processes which required enormous quantities of manual labor in past decades. ... Many scientists are already attempting to develop treatments that effectively reverse some processes of aging."
