How large (program length ?) a Turing Machine would you need to think ?
Is complexity an issue with human thinking ?
Is the brain's memory large enough to hold a lifetime of experiences ?
"The human brain consists of about one billion neurons. Each neuron forms about
1,000 connections to other neurons, amounting to more than a trillion
If each neuron could only help store a single memory, running out of space
would be a problem.
You might have only a few gigabytes of storage space, similar to the space in
an iPod or a USB
flash drive. Yet neurons combine so that each one helps with many memories at a
exponentially increasing the brain memory storage capacity to something closer
2.5 petabytes (or a million gigabytes). For comparison, if your brain worked
like a digital video
recorder in a television, 2.5 petabytes would be enough to hold three million
hours of TV shows.
You would have to leave the TV running continuously for more than 300 years to
use up all that storage. "
