That’s at least my hypothesis. Looking at the grand scheme, I’d say they’ve been polluting everything for such a long time with microplastics, heavy metals, graphene, PEG hydrogels and GMOs in order to have the necessary ingredients these nanostructures need in order to assemble. From plastics to food to sky painting to injectables and shedding - it’s probably everywhere. 5G/mmWave brought in the microwave frequency spectrum for control of the stuff within the body and MIMO + beamforming is used for individual targeting.
