Comment: In late 1980s and early 1990s, I took one of the first Computers in the Classroom courses offered at the Education Faculty of York University in Toronto, Canada. In a disussion that followed, our instructors shared a story about new nanotechnology that was being developed at that time. This technology used extremely small chips made with the use of laser beams and certain bacteria that align with these beams and can be “frozen” to form conductive paths (printed circuits). It was hoped that, aside from military applications, this technology would be used to manufacture miniature robots able to flow with the blood and remove blockages causing heart attacks and strokes. A few years later, the technology was classified. It is possible that today’s nanotechnology injected with vaccines is a result of this research, with one difference. It is designed to kill people, instead of helping them. My opinion.
