How can we prove that fact? Very symple, show something that used to be modern a few years ago to a today's kid and stare at his reaction! That's what "the fine brothers" have tried with the eighties' computers.
Don't miss this funny video. First you can see they don't even know what's standing in front of them. When they reach the conclusion that that's a computer, they wonder how to turn it on, and once on... They know anything about how to use it! (Honestly, I wouldn't know neither) the first thing they look for on it is obviously internet. Mistake! There was no internet back to that time:) after that, they play with it a few minutes and quickly get bored of it.
It is an interesting experiment, and I have to say that there were two sentences that stuck to my mind. Thi first one, has a sense of humour: it looks so hipster! The other one, worried me a little: if there was no internet, how did they do their school work? This means that young generations are completely forgetting about books... Do we really want to be a society based exclusively on internet?
Internet is an undoubtable helpful tool, however, we can't rely only on internet. We must keep books and handwritten things as a treasure if we don't want our grandsons to need a keybord to write down anything.
