My first word processing program was Multi Mate 5. My first modem was 24 baud in 1990. I've had the same aol email address since 1995, which is practically unheard of.
In 2000, I easily navigated Netscape and backed up data redundantly on iomega tapes.
In 2 decades the entire world is different because of the change in the way we communicate.
Like Gutenberg. Did he know he was changing the world, by changing its communication? Are we being hopelessly old fashioned by supporting Catholic radio? Not really. People still have radios in their cars. Everyone can't afford satellite.
But its days are probably waning. What will be the next big thing?
Stay tuned. (Pun intended.)
