Good discussion here on consciousness with an actual definition with 3 levels and units of measure.
And the world is not predeterministic as Newton and Einstein formulated, due to Quantum Mechanics theory that contains uncertainty.
Lastly, the brain is a biological machine, with its core being a Neural Net, with Neurons firing Ions across synapses, that occasionally leak. And criminal minds are to blame for the criminals actions, defective.
Says computers will eventually pass the Turning test and be slightly less than an actual human brain, very indistinguishable.
And people have been trying to mimic the brain using computers, which is incorrect, should be using Neural Nets that can learn and rewire themselves from time to time.
Have a listen~!
