The most important thing invented in my life time I believe is computers. Computers have allowed society to process and advance procedures in business. The next invention would be the purchase of electric and flying cars. I hope that I will be able to one day before I die be able to go in and buy a electric flying car. The next and last thing in my life time would be the space hotel for trips for society. They are predicting by 2036 I think that will be up in space. So maybe ! Fingers crossed.
