Mind-Boggling Devices Around the World

I find it very interesting that similar technology is discovered around the world. That in it's self you would think would be huge news, HUGE.

What would it take for today's technology to look mysterious in the future? Serious tell me. Cell phones, nuclear weapons, farming. How would these things be described in a 1,000 years?

Will the world forget these thing and be so advanced that it in inconceivable how a cell phone works, or will the future generations think they are mentally advanced yet far behind where we are today? As such I do find videos like this intriguing!
