Many Americans, especially those who are highly religious Christians, express discomfort with techniques that in some cases blend the human body with machine-enhancements like brain chip implants, according to a Pew Research Center report.

Among U.S. adults with a high level of religious commitment, 81% say that the widespread use of computer chip brain implants for faster and more accurate information processing would be “meddling with nature and crosses a line we should not cross.” In contrast, Americans with a low level of religious commitment are evenly divided on this question: 50% say that brain chip implants cross a line that should not be crossed, and 49% more closely identify with the notion that “we are always trying to better ourselves and this idea is no different.”
