Transhumanism aims to enhance human capabilities through technology, but this raises issues that require global cooperation to address. The rapid advancement of technologies that could augment the human body and mind may profoundly impact society in the next 15-20 years before people are prepared. All nations must work together to 1) raise awareness of potential problems, 2) limit artificial evolution research due to risks, and 3) focus technology on helping the sick rather than altering baseline human abilities, to avoid inequality, unrest, loss of free will, and other threats to human nature and global stability. Failure to do so could divide society and endanger the human race.
