I have lost all but a little vision in one . Eye. have nothing but blackness in the other. For a long time I set about being the techiest 83 year old on the planet , trying to master AI before I was too blind to use a little visual to help. My attitude toward all this was to try and be a normal person. After reading Andrew’s experience particularly the several weeks he spent with a sleep mask learning to navigate the world completely blind, I stopped competing with normal people and embraced the attitude of being the best low partial I can be. Thanks.. Just a shift in perception makes a big difference.
