Back to the Future Day: Doc Brown on why we have no hover boards
Or flying cars and a proliferation of fax machines
Today, October 21 2015, is the day that Marty McFly and Doc Brown travelled to in the future from 1985 and the mad scientist has explained why there is not some of the advanced technology around that was in the film.
In the second installment of the famous trilogy, Doc Brown (Christopher Lloyd) and Marty McFly (Michael J. Fox) travel 30 years into the future to a world of self-tying shoelaces, hover boards and flying cars.

There is no mention of Facebook, Twitter, iPhones or even the internet.
Although they did have electric cars - that were able to perform a vertical take-off and use highways in the sky to get about.
And fax machines were seemingly the main mode of communication.
As a response, Doc Brown has given a clue as to why the film was a little off-key with its predictions.
"It just means your future hasn't been written yet," said the Doc in a short feature marking the day.
Directed by Robert Zemeckis - who was also behind classics such as Forrest Gump and Who Framed Roger Rabbit - some $40million was spent on the film.
It made a box office return of a staggering $332m, making it the third most popular film of 1989 behind Batman and Indiana Jones and the Last Crusade.
Michael J. Fox and Christopher Lloyd were recently brought together to discuss what the film predicted.
“Can you believe we thought fax machines would still be around?” Fox tells Lloyd in the footage.
