Brain Control, Havana Syndrome, Microchips, USA and China
The original stuff was Russian, designed by Theremin, used for passively eavesdrop a room, then USA decided to upgrade it to target back, With a bit of neuroscience and nanotechnology in it.

It is just a tiny tiny microchip inserted in a cavity with direct contact with a nerve.
Made by NSA/GCHQ, used by CIA/FBI/NSA.
Can be used to read thoughts (ideas), induce dreams or remotely to torture a subject, electric shock sensation included ( like electric chair, pretty funny if you can tolerate pain... I can )
Do you really think Bill or Elon have all the ideas themselves? Not.
Expensive stuff.
I have a working sample of the microchip in my possession.
That's why intelligent folks need to remove the microchip before decrypting serious stuff or giving serious information.
And now USA does not want China to have the same power.
