The Vigilant Fox article (link below) presents an alarmist take on emerging neurotechnology, dystopian risks, e.g., mass non-consensual implantation via injections.
In November 2025, MIT researchers (led by Deblina Sarkar of the Nano-Cybernetic Biotrek Lab) published a study in Nature Biotechnology on "Circulatronics" — a platform using microscopic wireless bioelectronic devices called SWEDs (sub-cellular wireless electronic devices). These are tiny (subcellular scale, far smaller than a human hair's ~70 micrometres width; devices are on the order of micrometres or less, with some descriptions noting billionths the size of a rice grain).
How it works: SWEDs are photovoltaic (light-powered), wireless electronics hybridized with living immune cells (monocytes). Injected intravenously (via standard syringe into the arm), they travel through the bloodstream. The immune cells guide them to sites of inflammation in the brain (e.g., in models of neuroinflammation), where they autonomously self-implant. Once there, they deliver precise electrical stimulation for neuromodulation — potentially treating conditions like Parkinson's, epilepsy, depression, or other neural disorders without open-brain surgery. So, the sales pitch goes.
Key advantages: Non-surgical, targeted (high precision, ~30 µm), biocompatible (cells "camouflage" devices from immune attack), and focused on inflamed/diseased regions.
Current status: Demonstrated in mice only (as of the 2025 paper). No human trials reported yet. Emphasis is therapeutic, not enhancement or AI connectivity. The devices stimulate neurons electrically but aren't described as full brain-computer interfaces (BCIs) for bidirectional data transfer or direct AI linking.
This builds on prior MIT work (e.g., ultrathin flexible fibres or needles for drug delivery/optogenetics from 2017–2018), but Circulatronics is a leap in non-invasiveness.
Nicolas Hulscher's Warnings
Epidemiologist Nicolas Hulscher is quoted warning (link below) that such tech "raises an unsettling possibility" of deployment without realization — implying covert mass injection (e.g., via vaccines or routine medical procedures). He frames it as a path to uncontrolled surveillance/control. At present there are tech limits: The devices require specific design (cell hybrids targeting inflammation), intentional injection, and aren't stealth-deployable at scale today. But it is the first step along that road, and be sure that the elites will do it if it can be done. Just look at their track record, including COVID.
