I am serious about this: is there any sense in us all learning sign language? Or would our control of our hands just be the same problem with signing as with typing or writing with pen or pencil?
Most likely i suppose it will be some computerized app whereby a computer speaks for us.
There must be a lot of research somewhere - when some of us get cut off from communication with the human race, I would think that would be looked at somewhere. Or have researchers not noticed yet that there are patterns of people who are obliged to fall silent?
It would behoove the human race to pay some attention to those who get closed off from communication and then from interaction.
