This is so inspiring, awesome and uplifting. Just great that talented engineers are doing so much to help the blind gain some sight. Way back, when I first joined IBM, in the mid-1970s, I tried to do my bit. But, that was nothing. Nothing like this. So, glad. So, happy. Being in total darkness cannot be much fun though these brave people tough it out. Just seeing some light and some shape, to begin with, has to be such a relief. Literally, light at the end of the tunnel.
Second great story in two months. We must be making strides. I am delighted. Savor. Share. Contemplate.
