Ending natural biological death through rejuvenation means overcoming one particular biological limitation. In that sense, ending death is not much di erent than many other technological advances that overcome some part of our limited biology. The bene ts of ending natural biological death are potentially immense. However, even though rejuvenation technology should be pursued and implemented as soon as possible, there are some risks that should be taken into account early on. Primarily, we need to address the problem of potential unequal access to and the monopolization of the rejuvenation technology.
