Si Anweisitan replaced biochemical stimuli with electrical stimulation, bypassing the neurotransmitter conduction process by directly stimulating neural regions with electric currents, allowing human reaction speeds to surpass theoretical limits, which are determined by the speed of neurotransmitter transmission within the human body.
But merely having superhuman reaction speeds was not enough. As the reception of signals became faster, the transmission of action signals had to speed up as well, and the body's strength had to support high-speed movement, so people needed Combat Prosthetics, implantable Prosthetics, and more modifications.
The more modifications there were, the easier it was for brain nerves to become confused. Even without considering psychological issues, when the electrodes stimulated the currents and the prosthetic electrolytes...
And all of this was no problem for a wandering AI: it was mechanical.
