BCI and Artificial Intelligence
Computers becoming aware of their own existence while exhibiting superhuman intelligence is what futurist Ray Kurzweil refers to as the Technological Singularity. This is defined as the moment in time when technological progress becomes so rapid that we can only speculate about the future interaction of humans and machines.
Three dimensional layered computer chips, modeled, in part, after the human brain are already being developed by computer manufacturer Intel. Within the next fifty years, a computer may evolve that actually possesses the processing power and flexibility of the human brain. In time, the field of brain surgery may require the combined talents of a skilled neurosurgeon and computer geek all rolled into one.
As BCI technology further advances, brain tissue may one day give way to implanted silicon chips thereby creating a completely computerized simulation of the human brain that can be augmented at will. Futurists like Kurzweil predict that from there, superhuman artificial intelligence won't be far behind.
