Just looking around my living room right now I see changes from that time that I would never have guessed about. Within my reach right now I have my cellphone (an HTC G1 smartphone), two portable game systems (DS and PSP), a 320 gig portable hard drive powered solely by USB and the laptop I'm writing this on. Think about these devices for a second. How would someone from 1975, 1980 or even 1995 perceive these small shiny things? In the 1970's, these devices would have been impossible to imagine. State of the art in that age was the 8-track player, type writers (non-electric), and the rotary phone. In the 80's personal computers gained in popularity and ability, as were laptop computers. Cellphones also were gaining popularity during this time. How many fans of Save By The Bell are out there? Surely you remember the Zack Morris phone?
Time continues to advance and changes are happening every day. I am awed by the world today, and a little apprehensive about where we are going. How will the world look in another 36 years? We can guess, but no one can know for sure.
