Transhumanism aims to use science and technology to enhance human capabilities and overcome biological limitations. It could allow humans to significantly extend their lifespans through interventions like replacing failing organs with artificial ones, combating aging at the cellular level, and transferring one's consciousness to a computer. However, others are more skeptical of such predictions and believe longevity increases will be more modest. The future of transhumanism and its impact on human evolution remains uncertain and raises ethical issues that require philosophical consideration.
