Processing with Neurons
   - People do all of their processing with neurons.
 
   - How can we do processing with simulated neurons?
 
   - We don't know all of the details about how people process
       with their neurons, but there is some evidence.
 
   - Moreover, we've used simulated neurons enough to know that 
       given enough neurons, you can program anything that can 
       be programmed.
 
   - Neurons are Turing complete.
