You cannot control fully someone else's brain wiring

Krishna: Brain wiring refers to the complex network of more than 100 billion neurons and more than 150 trillion synapses (the connectome) that form the structural and functional connections in the brain. During development, axons are guided by molecular cues, establishing precise, stereotyped, small-world networks. This architecture supports cognitive function but remains plastic, allowing for rewiring based on experience, learning, or recovery from trauma.

The brain is not static. It constantly rewires itself based on experience, a feature critical for memory and learning.

Fully controlling someone else's brain wiring is not possible in the present situation although you can influence and retrain it to some extent.

Currently, it is not possible for an unknown entity to fully control another person’s brain wiring, though science can stimulate, monitor, or temporarily alter specific brain functions using electrical signals. While neuro-technologies can create sensations, treat disorders, or read intentions, complex "mind control" is scientifically impossible today due to the brain's massive complexity. ​

Current Capability: Scientists can use neurotechnology to trigger sensations (e.g., tingling, movement) or treat medical conditions by stimulating specific brain areas.

Inputting Information: Technologies like cochlear implants or optogenetics can inject signals into the brain to restore senses.

Why Full Control Isn't Possible: The brain consists of 90 billion neurons functioning in massive, complex networks. It is a "state machine" that cannot be easily overwritten like a computer.
