There are a number of very suspicious things that occurred this year. Charles Lieber and a few Chinese nationals were arrested due to fraud and scientific espionage. China maintains a program called the "Thousand Talents Plan", which is designed to recruit foreign scientists with bribery and convince them to divulge proprietary information to the Chinese, giving them a strategic technological advantage.

Charles Lieber has been working at Harvard on silicon nanowire tech for the past 22 years, and with nanotech and nanoscale structures in general for even longer than that. He was arrested All of his publications are readily available:

Many of his papers describe using silicon nanowires as the basis of BCIs, or brain-computer interfaces, a.k.a. "Neural Lace" tech, like Neuralink (which is similar, but uses electrodes that are much larger and much more primitive than nanowires).

Silicon nanowire field effect transistors, or SiNW-FETs, are transistorized silicon nanowires. They're extremely small, on the order of a few micrometers long by a few nanometers thick. They are small enough to be coated with HIV TAT peptides and slipped right through the membrane of a cell.

Once inside, they're capable of reading signals from (and modulating the activity of) individual neurons. How does one power them if they're inside cells and have no batteries, capacitors, or other power source? Simple. RF induction.

What device is capable of directing RF of the required frequency directly into someone's head? A phased-array beamforming antenna, capable of steering beams of RF towards anything with high precision. What uses phased-array beamforming antennas? Fifth-generation wireless cell networks do.

They even have a 600 MHz band in their bandplan that can penetrate tissue very deeply (millimeter-wave frequencies only penetrate the skin to a depth measured in millimeters).

Just one little problem left. How to get the nanowires into the brain, past the blood-brain barrier. Normally, the BBB keeps foreign objects out of your brain tissue. There is one thing, however, that compromises the BBB very handily. SARS-CoV-2 Spike proteins. You see, COVID-19 is a vascular endotheliitis. This virus attacks the lining of people's blood vessels. That's why it causes blood clots, heart attacks, pulmonary edema, and all these other weird symptoms that one would never expect from a pneumonia. Its manifestations are protean because blood vessels are everywhere in the body. This is why it seems like an "everything-virus" that can impact every organ; it can cause viremia and inflammation in many different vital organs, as well as aggressive coagulopathy and neutrophilia.

SARS-CoV-2 Spike proteins, on their own, even without the rest of the virus (even the shed spike proteins) can injure the blood-brain barrier and make it more permeable.
