I remember during my elementary days when computers used to be family computers with variety of cartridges to choose from. The desktop computers then was DOS based and uses diskettes as memory devices for storage. It had a little impact to my childhood because studying was my main priority, I play family computer about once a week, and desktop computers were still not on my interest. During my high school days, nintendo, sega, and playstation became popular and it was the best computers to play with, and it became my hobby already, consuming most of my spare times. Early Microsoft windows versions was becoming useful as well, but I was still not interested for the fact that I was not still familiar with it. I ignored it. And then came my college days when the evolution of desktop computer games and applications were evident, I learned a lot about desktop computers and basic softwares in school and it had made huge impact on me, from working to playing games for consoles. Now, computers do most of our jobs than ever, it became a very useful in working, and online games do part as well. For me, humans became dependent to computers simply because computers can do a lot of jobs with ease, but still not too well dependent I guess. In your point of view, are humans too dependent on computers? How and why?
