As you probably already know, today is Back to the Future Day.
Right on cue, astrophysicist and Cosmos host Neil deGrasse Tyson is taking to Twitter to fact-check the movie's vision of the year 2015.
As it turns out, Back to the Future Part II got a lot of things right. We have video chat!
Our cameras are even better than imagined.
However, there are plenty of things that were just too much to hope for.
Like robotic dog walkers, for example.
Or a handy Mr. Fusion.
Or flying cars, which we might be better off without. The only thing worse than road rage is ~flying~ road rage.
Neil has a BTTF prediction or two that he wishes were real.
And some that he wishes had been wrong.
And a couple that are just...no.
No no no.
