Cognition, Computers & Cooperation

• Forecasting technology for the Army

• Pitfalls of futurology

• A little about the human brain

• Machine-driven thoughts

• Thought-driven machines

• Brain to brain communication


3


• The failure modes of futurology:

− Scientific discoveries are unpredictable.

− Technology breakthroughs are no better.

• significance

• omission

• alternatives

• What makes this prediction different?

• It does not start with the desired outcome.

• It is based on reasonable extrapolation from existing sciences.

• It synthesizes the results from three fields.

• This is only one of many potential outcomes.

Brain-computer interface (BCI)

Network Science (NS)

Synthetic telethaphy

50 years

15 years

Brain-brain interface (BBI) 15 years

Let us start with the experimental evidence that:

1. machines can directly influence the brain;

2. the brain can directly influence machines.

• Brain-computer Interface (BCI) experiments gained notoriety in the spring of 1965, when the Yale neuroscientist Jose Delgado stopped a charging bull by transmitting a radio signal to an implant in the caudate nucleus of the animal’s brain.

• First brain-to-brain Interface (BBI) experiments involved two rats.

• Encoder is the sender and decoder is the receiver

• Encoder learns empirically

• Decoder learns by having information funneled into his brain directly
