When I was young , Dad used to get Popular Mechanics Magezines , which would predict what the future was likely to be like . It had some amazing forecasts , some of which did come true , some are now possible , but not in general use , yet , at least .. This is an amazing time to be alive . I had a little old maid Aunt who could remember the very first time an automobile came to Laurel , the city she grew up in , between Washington D.C. and Baltimore , Md . She lived to see man walk on the moon . When I was small , my parents bought an old used car that had both a key ignition starter and a long crank as a back up system for starting the car . Now there are self driving trucks and cars on the roads . They had an old TV someone else was was getting rid of , that had a screen that measured about 5" diagnoly . now you can buy a screen that is relatively flat that takes up most of a wall .
