Transhumanism is a movement that suggests that humans should use technology to improve themselves. People who believe in transhumanism think that technology can be used to improve things like our physical and mental abilities, so that we can be smarter, stronger, and healthier than ever before. For example, transhumanists believe that in the future, people might be able to replace their body parts with robotic ones, or add artificial intelligence to their brains to make it better and faster.
