Is email really 30 years old? Nope. It’s more like 47 years old. Technology historian Thomas Haigh sets the record state in an email to David Pogue:
Email, or electronic mail, is actually at least 40 years old, and the NY Times itself has documented its use in 1965 (47 years ago). Hence, collecting endorsements for the “30 year anniversary” claim, i.e. 1982 as the origin date for email, is an key strategy for Ayyadurai.
47 years old. This is a channel we all still use to communicate.
