Look at the person sitting to the left of you. Now look at the person sitting to the right of you. Is either of them wearing a high-collared full-length trench coat or a wide-shouldered black boxy blazer?

If the answer is "no," you've just discovered one of the things 1982 sci-fi classic Blade Runner got wrong about the "future".

Because that future is right now — today, in fact. The Harrison Ford film, based on the Philip K Dick novel Do Androids Dream of Electric Sheep, is set in November, 2019.

The Ridley Scott classic tells the story of Rick Deckard (Ford), a world-weary cop whose job it is to hunt down and "retire" replicants — robots that are so human-like they've started believing they should be left alone to live their lives like everyone else.

We can now officially say the fashion of Blade Runner, inspired by 1980s punkish elements and the noir films of the '40s and '50s, is not what people are wearing in 2019.

But if we're going to play the game where we pretend the main job of science fiction is to predict the future, rather than to tell thought-provoking stories, what else did the film get wrong ? And what did it get right?

The climate is changing

For starters, our planet is pretty cooked, as foreshadowed in the movie.

Without addressing the state of the environment directly, there is a strong implication that climate change is wreaking havoc on the world and making the daily lives of the characters pretty unpleasant.

The rain over Los Angeles, where the movie is set, is omnipresent — there isn't an outdoor scene where it's not pouring down.

Though scientists tell us we are plummeting towards climate disaster, we haven't reached never-ending downpour status.

Nor is all animal life virtually extinct, with artificial replacements offering the only faunal exposure.

The only animals in Blade Runner are fake ones. ( Blade Runner )

And we are pretty far off setting up off-world communities in order to escape a declining Earth. Hooray.

Though the ever-ambitious Elon Musk is insistent we should soon be setting up colonies on the Moon and/or Mars in order to carry the torch of human culture forward.

"We are building the first ship, the first mars, or interplanetary ship, right now. And I think we'll be able to do short up and down flights in the first half of next year," he said … last year.

Getting to Mars would result in "an explosion of entrepreneurial opportunity," including "iron foundries and pizza joints," he mused.

Using voice commands with computers …

… is something we do.

In one scene, Deckard tells some kind of steampunk Photoshop program to gradually zoom in on a picture.

It's only fairly recently that we have been able to chat to our special phone friends Siri, Alexa etc, and ask them to perform various tasks for us.

What's patently wrong about this scene, and all others involving computers or TV screens, is that the technology all looks very clunky, lo-fi and 1980s, and nowhere up to the standard of modern smart screens.

And a yawning gap in Blade Runner's depiction of tech is the lack of anything resembling a smart phone — a gizmo which has become ubiquitous in the modern world, and does most of our daily communicating and computing for us.

There is even a scene where Deckard goes into a public phone booth to make a video call. Good work on the Skyping prophecy, not so much on the belief in the continued relevancy of phone booths.

We'll never know if Deckard is one of those people who hates receiving calls and prefers to text.

We need to talk about flying cars

The Jetsons promised we would be zipping around in flying cars some time soon. ( The Jetsons )

It's hard to say whether science fiction writers or real-life scientists and engineers are to blame for this one, but sci-fi movies have repeatedly got it wrong.

Maybe we should blame the Jetsons for starting it all, but folks need to stop promising that this is just around the corner.

Then again, drones are becoming commonplace and Uber Air taxis are meant to be coming soon, so maybe flying cars are just around the corner.

Then there are the replicants

Modern science has got as far as producing sort of life-like sex dolls, or specimens like Hanson Robotics' "Sophia", which uses advanced algorithms to engage in conversations — but they are a long way off the replicants in Blade Runner, which are virtually indistinguishable from real humans.

The whole tension of the plotline revolves around the ability to identify replicants, which is done using another rustic-looking computer to perform the "Voight-Kampff Test" to expose their lack of empathy.

In our 2019 we use CAPTCHA technology to identify bots — a test which regularly bamboozles actual humans (Is that a lane or a road!?) while failing to eradicate fake accounts.

A CAPTCHA test to identify real-life people. But what constitutes a road?

Advertising is indeed very … in your face

Perhaps the most spot-on element of modern life shown in Blade Runner is the overbearing advertising.

Ridley Scott's Los Angeles is awash with obtrusive, vast electronic billboards, long before they became commonplace.

The movie only gets some of the brands that have stuck around right, though.

Yes, the likes of Coca-Cola, Budweiser and Tsingtao are still going strong, but Pan Am and, sadly, Atari are no longer around (the Atari of today is a completely different company).

How does Blade Runner's vision of the future compare to other films set around now?

The Running Man didn't get much right about 2019.

Blade Runner does as good a job as any at predicting the future, compared to many of the other sci-fi movies which time has caught up with.

For a start, most assured us we would be living in a dystopian hellscape by now.

Say what you will about the state of things, but it's not quite as bad as most of these movies would have their audiences believe.

1987's The Running Man depicts the United States of 2019 as a totalitarian state where reality TV has become an obsession and fake news is ubiquitous. Insert your own jokes here.

Arnold Schwarzenegger's character is a prisoner who has the chance to win his freedom by taking part in a state-sponsored show in which he is hunted for sport.

The computer graphics in The Running Man aren't quite up to today's standards. ( The Running Man )

Once again, the technology on display looks completely archaic by today's standards, with cassette tapes and analogue phones still prevalent and computer graphics still stuck in Commodore 64 territory.

And while The Bachelor can get pretty brutal at times, reality TV has not yet reached homicidal levels.

The Ewan McGregor-Scarlett Johansson movie The Island was also set in 2019, though having been made in 2005, it obviously had an easier job of predicting the future.

Still, though, the world is a messed-up place where people live and work as slaves in a cold, soul-less facility. The only thing they have to look forward to is winning a lottery to earn transportation to an island paradise. Spoiler alert: there is no island paradise.

Michael Bay and his writers must have had a very bleak outlook if they thought that in 14 years' time there would be facilities set up to harvest human organs for celebrities. Worst of all, everyone wears generic white jumpsuits. Shocking.

Finally, though it was set in 2015, it would be remiss not to mention Back to the Future II, made in 1989.

Apparently everyone in 2015 wears bright colours. ( Supplied: IMDB )

Hoverboards are almost up there with flying cars when it comes to mass disappointment that they haven't yet been invented.

And yes, the fashions are utterly bizarre while technology looks ancient by today's standards.

They did nail some stuff, like fingerprint identification, video chats and drones.

But on the other hand, lawyers have not actually been abolished, your grandparents are probably the only people you know who still have a fax machine and we're nowhere close to Jaws 19 yet (they should have bet on Rocky for longevity).
