What dangers are there for a society which depends on computer screens rather than face-to-face contact for its main means of communication?

Answer 1

One of the dangers of communicating between computers is that the traffic between them can be intercepted by a third party. Unless the information is encrypted, secrets between two companies can be read by a competing company, which could use the information for its own good. This is a relatively small risk in computer communication today however because of the use of Diffie-Hellman key exchange, or similar variations, between the two parties. Information can, using this method, be encrypted so strongly that it would take all the worlds computers combined millions of years to crack it.

Answer 2

That is not danger. Using computer to communicate is not effective. That differs so much with contacting face to face. In computer, communicating and seeing each other is not clear. Communication using never replaces face to face contact.

Answer 3

Well not many extreme dangers. But lack of social contact with other people might be the most major one of all.
