Not long before my great-grandmother died some 10 years ago at the age of 100, she and I were cataloging the vast amount of technological change she witnessed in her lifetime. From the first flight to two world wars fueled by heavy industry, to the Space Age and laptop computers, her lifetime spanned probably the broadest technological change we're likely to see.
Changes that we'll see over the course of our lifetime will likely be limited to knowledge- and information-based changes, but they'll be just as mind boggling. This video, called Did You Know, more than any other I've seen, truly captures what a remarkable age this is.
