14. Conclusion
BCI is an advancing technology promising paradigm shift in areas
like Machine Control, Human Enhancement, Virtual reality etc.
so, it is potentially high impact technology.
Brian Johnson CEO of Kernel(a company developing neuroprosthetic device)
has said on Black channel -
We are now in the era of self-directed evolution. Genetically,
biologically, neurologically, and physically. I’m just waiting for
a nation-state to raise its hand and say –
“We are the home for human potential.
Bring your technologies and let’s do it.”
