It sounds that current human beings are communicated orally. Any human speech can be encoded with very high accuracy in 8kb/sec data rate.
Now let us assume that we have two persons, the first person speaks and the second person listens. If the listener captures everything without any loss, the effective data transmission rate between these two users is roughly 8kb/sec.
I have now two questions
Will human beings evolve to have brain to brain communication (without any electronic interface)?
If yes, what will there be the data rate limit of Brain to Brain communication?
This will also raise a question whether the original purpose of “mouth” is for communication or not?
Any insight is appreciated.
