The term 'Not Entirely Human' can be summarized by the word 'Bionic', which is a six-letter word. Bionic refers to a person or animal that has been enhanced with mechanical or electronic components, such as artificial limbs, organs, or other body parts. This technology has been used to improve the quality of life for people with disabilities, and to give them greater independence. It has also been used to create superhuman abilities in some cases. Bionics is an ever-evolving field of science and technology, and it continues to be explored and developed.
