If you missed Back to the Future Day, well shame on you! Your nerd status must be called into question.
Sure, we didn't get the totally awesome hoverboards or leashes that walk the dog by themselves, and luckily we didn't have to experience Jaws 19. We did get video telephone calls though.
Even if the iconic film's predictions of what we would have by October 21, 2015 didn't exactly pan out as we would all like, it had me reflecting on things we DO have, especially what my generation's grandparents and parents have seen in their lifetimes already... how about not having to crank your car to get it to start? And from records to 8 track tapes to cassettes to VHS to DVD to digital. Do you remember how much space 20 VHS tapes would take up? Stores selling CDs will be practically non-existent soon, and then DVDs (RIP Blockbuster). Although most advances have been purely for human entertainment (TV, video games, e-books, movies), I'm making my predictions (and hopes) for 2050.
The newest wave I hope will continue to be on renewable energy and environmental impact (here comes my tree-hugger side). I would hope in 2050 that all cars no longer ran on gasoline, either electric or renewable products. Sure, if cars could fly like the Delorean, that would be awesome.
I want everyone to recycle the basics and all the landfills to be disappearing and using methane gas.
I want to be able to tell my grandchildren, "When I was your age, we had to stop at a GAS STATION to refill our cars and you had to pay for a service called AAA to come pick you up because sometimes you would run out of gas and your car wouldn't work," and have my grandchildren gawk at that.
