I agree with you. Just because it is decades old technology doesn't necessarily mean it has to be replaced with something. I have observed that the familiarity and usage of email among teens is alarmingly low. Then again, I don't see any better alternative to non-realtime, guaranteed delivery, suitable for both formal and informal communication and can-handle-all communication protocol like email. Perhaps todays teens will lead the way for building the alternative to email.
