Regarding devices that can control humans, there is no known device that can fully control human thoughts or actions. Mind control is a complex and controversial topic that involves ethical considerations and raises concerns about individual autonomy and consent.
While certain technologies like brain-computer interfaces (BCIs) exist and are being researched for medical and assistive purposes, they are typically designed to help individuals with disabilities communicate or control devices through their brain activity. The idea of mind control, as portrayed in science fiction, is currently not a reality, and any claim of such a device should be viewed with skepticism.
It's essential to be critical of any extraordinary claims or devices that promise mind control, as they are likely to be based on misinformation, pseudoscience, or unethical practices. Always seek reliable sources and scientific evidence when exploring such topics.
