The Singularity is a theory or school of thought that is premised on the increasingly rapid (exponential) pace of change in technology development. Singularity advocates describe a point at which technology developments will render a future for human life that is dramatically different than anything we have known or experienced up to that point. Among the proposed implications of this point of technological demarcation is a radical extension in human longevity. Some Singularity advocates believe that technology will enable extreme longevity and even immortality.
