       | materials trying avoid to forget what it already learned.

       | Holy cow, what a leap. What if neurons _don 't_ work like
       | memristors? What if neurons are more like tiny FFT circuits,
       | working on firing rates, integrating over time, encoding
       | information into frequencies? What if the molecular structure of
       | the insides of neurons works more like a forest of tuning forks
       | and can use molecular computers to do analog, approximate
       | calculations that we're simulating with GANNs using weights?

       | they are in a Matrix until they are deemed ready.

       | ...high as balls maybe?
