In my lifetime we've sent a man to the moon and music has moved from records to 8-tracks to cassettes to CDs to MP3 players. But what hasn't changed. The vast changes have been in computation and communication, but transportation remains mostly the same. Airplanes fly as fast now as they did in the 60's using the same basic jet engine technology. Most cars still run on the combustion engine and remain grounded. Elevators, escalators and sidewalks where people still walk. We really haven't changed how we get from point A to point B.
We still read our books on paper and write with ballpoint pens. Locks are mostly split cylinders. They still haven't invented a good mouse trap or cured the common cold. And let's not forget the greatest device devised by man: Saran Wrap.
