Artifacts of the future reflection

From looking at all of the predictions of what will be in the future(now) and their fulfillments. My favorite fulfillment that went through was when back to the future predicted about the hover board. Lexus has put out a hover board that actually works but it is not as practical as the ones from the movie, considering that you need liquid nitrogen to keep the board from over heating. Overall I think that the fulfillments that went through are pretty accurate just not as animated as it was in the predictions. Lastly, I enjoy getting information from QR codes. It is like having live links of information anywhere you go and all you need to do is scan it.
