The most complex object in the known universe, brain, only uses 20 watts of power.It would require a nuclear power plant to energise a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts.So if someone calls you a dim bulb, that’s a compliment

The real bottleneck is software. Creating software can be done only the old-fashioned way. A human -sitting quietly in a chair with a pencil, paper and laptop- is going to have to write the codes... One can mass-produce hardware and increase it's power by piling on more and more chips, but you cannot mass-produce the brain.

The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

The brain weighs only three pounds, yet it is the most complex object in the solar system.

We physicists know that the brain is a milliwatt transmitter of radio. We have computers that can decipher much of this gibberish coming from our brain and we could then use that to control computers.
