Transhumanism is the position that humans should be able to use technology to enhance and modify human abilities beyond normal biological constraints. It aims to expand human cognition and bodily functions through means like biotechnology and cybernetics. Transhumanists see limitations in human intelligence and bodies and want to use technology to achieve more positive experiences. Examples of precursor technologies include plastic surgery, artificial limbs, and organ transplants. Transhumanism could develop further in the next 20-30 years through emerging technologies like bio-3D printing, brain-computer interfaces, and synthetic blood cells. However, its development and social effects will depend on the level of regulation and social attitudes toward human enhancement.
