My minor was computer programing, some 30 years ago. Remember Fortran, Cobol and Basic?
One of the sessions was to create a program detailing how to program your body to take one step. Another was to pick up a glass, and take a drink of water. Those acts proved to be immensely complicated, and no one got it right until after many tries.
That program to have the boy write a few words was amazing and way before it's time.
I don't suffer from any mental illnesses.. I enjoy them..
