50 years from today what invention will have the impact of cell phones or make something obsolete as DVDs have VHS?
When I look at my new at my new great nephew I wonder just what great inventions will happen in his life time. When I remember back over my own life all the marvels that have been created. The world went from super 8 cameras to VHS and now we are all the way to digital video all in about 30 years and change. The world went from no personal cell phones to just about every Tom, Dick, and Harry having one. The computing power of PCs today is miles ahead of computers that use to occupy whole rooms if not more, back in the 60s early 70s. I remember when they came out with the concept of the Space Shuttle in our grade school science news paper and I was thinking “A rocket that takes off like a rocket but returns like a plane, yeah right!” and they did it. 50 years from now what 3 things do you feel will be invented that will be game changers or render something of today obsolete as the CD pretty much done to cassettes and the DVD done to VHS?
