I actually think it is crucial for the future of mankind for people to have a basic understanding of how computers and the internet work.
These things have been out for long enough for so many people to still be so clueless.
Do I underestumate the average user?!?! No!!!! Overestimate! People around me never ever fail to dissapoint me with how little they know.
That is closer.
It would be like talking to someone that has had some type of computer for a decade and a half and having conversations like .... *go to your desktop* where is that *skrink your browser and then......* what is a browser?
OHMYGOD!!! That is close, I understand not know the finer details of the computer yet they should know that after a decade.
