The future of face recognition technology

October 2019’s issue of The Engineer featured an article discussing the controversy surrounding trials of live facial recognition (LFR) technology by South Wales Police and the Metropolitan Police.

Put simply, LFR technology enables a computer connected to a surveillance system to recognise individuals in real-time, which could allow those individuals to be tracked and behavioural profiles compiled. But while this kind of state scrutiny might set off alarm bells in those of us who have read 1984, there are implications to this technology that not even George Orwell could have foreseen.

As a science fiction writer, my job is to look not at how people will be using a piece of technology tomorrow, but to imagine what they might be doing with in it ten, fifty, even a hundred years from now.

So, what might the world look like by the end of the next decade if we assume that we’ll have LFR technology that’s sophisticated enough not to be easily fooled by sunglasses or beards, and cheap enough to be accessed by most organisations and even some individuals?

Perhaps your employer will require you to spend a certain amount of time at the gym each week in order to retain your health benefits. They will also know which shops you frequent and probably what you buy there, as well as how many times a week you visit a bar.

Investigators will be able to track the movements of cheating spouses. Self-driving taxis will recognise you and allow you to choose a destination from your ‘favourites’ list, while playing you a selection of music from your online playlists. Smart panels on the walls of shopping centres, offices and hotels will change not only the advertisements they display for you, but also the entire décor of the space you’re in.

But what happens if this technology gets abused? I’m not talking about a kind of Big Brother state panopticon, as that appears inevitable. Rather, I’m talking about more unscrupulous adaptations.

What if neighbourhoods and shopping malls refuse entry to known or suspected offenders? What if airlines deny service to customers they consider ‘high risk’ based on their ethnicity?

Journalists and stalkers could easily track the movements of celebrities using drones able to scan and recognise faces. On a more disturbing note, this technology could  be used for assassinations, allowing a drone carrying a few grams of high explosive to select and pursue a target.

Of course, the deployment of LFR technology will lead to the development of countermeasures. The most basic of these might be as simple as a large parka hood maybe paired with mirrored sunglasses or contact lenses that change the colour of the eyes, while more sophisticated methods could employ dazzle camouflage, using make-up to create optical illusions on the face, obscuring its exact proportions, or patterns that present as interference when viewed through a camera. One can also picture backstreet surgeons altering a person’s facial appearance in order to supply them with a new identity in a world where your face is your passport.

With the rise of deep-fake technology, it’s also not unreasonable to imagine the
ability for members of the public to 3-D print masks in the exact likeness of celebrities or politicians, in order to obscure their own movements or frame those individuals for crimes or infidelities. If identity theft in 2019 is a problem, imagine how much worse it would be if a criminal stole your face and used it to access your bank account, cast fraudulent votes, and maybe even place you at the scene of a murder.

Looking further into the future, we might consider the development of a self-aware artificial intelligence. What might such a creature do if it recognised the technicians who were coming to shut it down? Perhaps it might use some of the methods mentioned above to track down and eliminate those opposed to its existence, or those involved in competing projects. It might even seek out and kill its designers in order to ensure it remains one of a kind, unchallenged in its digital existence.

Moving The Moon

The Moon is often portrayed as a dead world, but it is rich with fictional potential.

Fifty years on from Apollo, most of the discussions around returning to the Moon focus on mining or colonisation. Both could be useful and even profitable enterprises, but are there other, more off-the-wall reasons to visit our celestial companion? Could the Moon help us fight climate change?

Lots of people have suggested covering the Moon’s surface with solar cells in order to harvest a lot of clean energy and beam it back to receiving stations on Earth. But why stop there? As a science-fiction author, my job is to take inspiration from today’s headlines and add a dash of wild speculation.

So, how about we make the Moon’s shadow larger?

Imagine building a 1,000km-high mast on the Moon, at the border between its visible and hidden faces. Now imagine building another 100km away, and then another. Eventually, you get the visible Moon ringed by these huge spikes, like a grapefruit with hundreds of cocktail sticks stuck in it. Now imagine we hang mirrored material between these masts. This would make the Moon appear much larger and therefore blot out the Sun’s rays over a wider area of the Earth’s surface, reducing the amount of sunlight reaching the Earth by a small but significant fraction.

Not wild enough? Okay then, how about we draw down the Moon?

Since its formation, the Moon has been gradually pulling away from the Earth at a speed of almost 4cm per year. Although that doesn’t sound like much, it is enough to subtly slow the Earth’s rotation, increasing the length of our days.

One-and-a-half billion years ago, the days on Earth lasted only 18 hours. Now, they last 24 and, in the far future, they may last even longer.

However, if we could use giant motors or near misses by large asteroids to move the Moon closer to the Earth, we could maybe reset this process, using a faster-orbiting Moon to increase the Earth’s rotation and shorten our days.

Why would we want to do that? Well, assuming we could withstand the resultant earthquakes and manage not to drop the entire Moon into the Pacific, the main effect of a shorter day would be that it would give the East and West hemispheres of the Earth less time to warm up in the glare of the Sun. The oceans would have less time to absorb heat, and winters would become colder. In addition, a faster-rotating Earth would give us faster-moving tides, which could have implications for tidal power generation – not to mention surfers.

But if we had such god-like powers of celestial engineering, why stop with simply moving the Moon? Why not find more Moons?

Manoeuvring asteroids and comets into orbits around the Earth would put their resources at our fingertips. I don’t want to start sounding like an eccentric billionaire trying to push a tech start-up, but asteroid mining would provide a cornucopia of ores and minerals, making the idea financially attractive. And if you’re mining material in orbit, it makes sense to process it on-site. You could also move heavy, polluting industries into orbit, decreasing the CO2 emitted into the Earth’s atmosphere.

All those little Moons would also provide more opportunities to create Sun-blocking mirrors to shield our atmosphere from heat. Imagine looking up at the night sky and seeing a ribbon of lights stretching across from one horizon to another, each one a small town or industrial installation.

As a pragmatist, this might sound like a lot of starry-eyed foolishness; but as a writer, the idea’s almost irresistible. It would make a great setting for a story. What would the people who lived on these tiny Moons be like? What kind of societies would they have? Would they be pioneers building a life in the sky, or contracted employees doing months-long shifts in orbit? Would they owe allegiance to one nation, to the whole Earth, or to themselves?

What sort of engineers would be needed in such a world? You’d need to be able to work and thrive in freefall. Perhaps you’d have physical adaptations to help you deal with the long-term health effects of living with reduced gravity. You’d certainly need to adapt your skills and techniques to working in a whole new environment; maybe you’d even need to develop some new ones.

Too often, the Moon is portrayed as a dead world. But with the right kind of imagination, we can see it’s alive with possibilities. The schemes I’ve outlined above are crazy, but as we face the reality of global climate change, the idea of finding a way to naturally cool the planet is an attractive one and moving the Moon would make a heck of a science fiction novel.

40 Recommended SF&F Books

The Californian bookstore Space Cowboy Books asked me to provide a reading list for their monthly newsletter, and this is the result.

When asked to provide a recommended reading list, I had to think hard. I didn’t just want to make a list of books that have meant a lot to me over the years, as many of them are now outdated. Plus, there are so many great writers and classic books that this list would need to omit many of them for the sake of brevity. I could probably have listed 500 books without too much trouble, so I have left out some of the more obvious ones, like Dune, The Hitchhiker’s Guide to the Galaxy or Do Androids Dream of Electric Sheep.

Bearing all that in mind, I present here—in no particular order—a list of books I’ve enjoyed, books I admire, and books I think every self-respecting modern SF author should read.

Getting my sh*t together

I am not a very organised person. I have a chaotic creative brain that doesn’t respond well to admin or accounting. Organising a Direct Debit payment is enough to bring me out in a cold sweat. But recently, I’ve felt the need to exert a little more control over my life. So, I’ve turned to technology.

I have an iMac desktop, an old iPhone and a MacBook Air. This means I can access the same files from all three devices. So, I now have a calendar and a reminder list I can refer to and update anywhere (with calendar appointments colour coded for work, social, home, birthdays, etc.).

I am also making use of the Notes app. I have various folders into which I can type story ideas, keep a list of my favourite Instagram hashtags, and generally download anything I need to remember. This is especially handy when an idea strikes while I’m out and about: I can make a note on my phone and know it will be there waiting on my desktop when I get home.

One of the biggest changes I’ve made has been downloading apps for my bank account, PayPal, and HMRC. Previously, I’ve recoiled from anything to do with money; now, I can easily keep track of what’s going in and out of my account.

And to top it off, I’ve even started using the Health app to track the number of steps I walk in a day and the amount of sleep I get.

I told you I was getting my sh*t together.

However, it’s not all a technological wonderland. For some reason, I find habit tracking easier in a paper journal than on a spreadsheet. So, I’m still tracking my daily tasks–writing, reading, alcohol consumption, housework–in an old school bullet journal. Something about colouring in the little squares by hand feels more satisfying than putting a tick in an Excel box. I don’t know why, it just does.

Are there any productivity or admin tools that you couldn’t live without? Let us know in the comments…


As you probably know, I have an Instagram account. It took me a while to really “get” the platform, though. It’s a lot less interactive than Twitter (where I spend most of my time), and therefore hard to judge whether you’re doing it right or not.

After a few false starts, I’ve settled on posting a combination of writing advice, books that interest me, promotion for upcoming releases, and behind-the-scenes shots from my walks around Bristol and other places.

My Instagram feed

I try to make each post interesting, or at least pretty to look at. I’m quite enjoying using my camera to capture quirky views. I’ve never been a big photographer, but it’s a fun creative outlet that kept me going through lockdown.

This isn’t really an advice column, as there’s still so much about Insta that I don’t know. Each of my posts gets around 40-50 likes, which means over 10% of my followers respond to each one, and that’s a higher level of engagement than I see on Twitter, where I’d need 3k likes per Tweet to get an engagement rate of 10%. Twitter feels more conversational and probably reaches more people, but my followers on Instagram seem to pay more attention…

I’ve no idea how to increase my Instagram following, though. My Twitter following goes up at a pretty steady rate of 200-300 per month, but my Instagram following has stayed more-or-less static for a couple of years. Any suggestions?

Beard Care

As a notoriously hirsute author, folk occasionally ask me to give them my top tips for taming their facial foliage. Especially now, as so many of you have grown beards during the lockdowns of the past year, and now want to return to work without looking like a Covid castaway.

Well, I don’t do anything fancy, but I’ll walk you through my routine.

The Essentials

  • A beard comb for straightening out those tangles
  • A good beard trimmer with adjustable cut lengths
  • Beard shampoo to keep your beard clean
  • Beard oil and balm to keep your beard and the skin underneath soft and conditioned


If you want to avoid a neck beard (and you really do), take the trimmer and shave away everything below a curved line that runs from ear-to-ear via a point about an inch above your Adam’s apple.

You can experiment with longer settings to keep the rest of your beard at a uniform length–although I keep the front of my beard (the goatee area) slightly longer than the rest, to lengthen the shape of my face and stop it looking so round (a beard can hide a multitude of chins).

Daily Care

After a daily wash with the shampoo, I comb out any tangles, massage in some balm and then apply a little oil to hold in the moisture and keep things shiny.

Et voila!

I told you I didn’t do anything fancy, but I hope that’s useful to those of you who asked for advice. Just a little time and care can keep the face fuzz looking clean and tidy instead of resembling a wild briar patch teeming with scruffy badgers.

It’s Okay to Reinvent Yourself

With all the media talk about getting back to ‘normal’ after the pandemic, it’s likely you’re feeling some pressure to reinstall your 2019 self and carry on as if the past year never happened. But we’ve been through a historical worldwide event, and it’s changed us. We’ve had months of intense isolation and psychological stress. If the you that’s reading this feels very different to the you of twelve months ago, that’s okay.

Change is part of the human journey. That’s why our films and novels feature characters who grow and develop as a consequence of their experiences. So, as we emerge from our cocoons, don’t let people make you feel bad for not wanting to be a caterpillar any more.

Covid-19 took a terrible human toll. At the time of writing, 2,961,282 people have lost their lives to the disease – a figure equivalent to the total population of Greater Manchester – and those are just the official figures.

You’ve had to absorb that scale of loss while taking precautions to avoid catching the disease yourself, so it’s no wonder your perspective might have changed. Things you thought important before might seem less so now.

Perhaps you’ve had time to re-evaluate your work/life balance. Maybe you’ve grown a beard or discovered a new skill or passion. Or perhaps you’ve decided life is too short and precarious to spend it doing something you hate.

Personally, I know I’ve changed. I’m tired but feel more comfortable in my own skin. I cut my own hair now. I feel more confident. A new chapter of my life is beginning and I feel ready to embrace it.

So, if you’ve decided you want to be seen differently and let people know you’ve changed, then do it. We only get one life, and we have to live it authentically, being true to who we are inside.

This doesn’t have to be a return to normal. Too much time has passed. Instead, you can seize the chance to make this a rebirth, a fresh start, and a brand new beginning.

Don’t Drink From The Firehose: Staying Sane on Social Media

Back in the early days of Twitter, I used to follow BBC Breaking News, Reuters, and several other local and international accounts. It felt good to be connected to the world. I could follow issues, debates and events as they unfolded in real time. At any hour of the day or night, I knew what was going on in the world.

It made me feel wired and in control.

The trouble is, in the constant barrage of social media everything is going on all the time. There’s no let-up or chance to pause for breath. No time to digest and reflect, just the constant bam, bam, bam of headlines and opinions hitting you twenty-four hours a day.

In that hellish melange, things get confused. Categories break down. Third-rate celebrities become political pundits. Experts get ignored in favour of conspiracy theories. Individuals and organisations wilfully sow disinformation until it’s hard to tell what’s true anymore. But if we look away for even an instant, we might miss something important…

During this pandemic, the barrier between home and work has become permeable. Adding politics and current events into the mix means we’re spending every waking moment in a state of stress, with our attention being pulled in three directions at once, and our emotions in a confused mess.

It’s hard enough being powerless in the face of Covid, the constant reminder of a thousand other ire-inducing issues we’re powerless to change leaves us feeling angry and frustrated and no longer in control of our lives.

And that just isn’t sustainable over the long-term.

As well as causing mental health issues, sustained stress can lower your immune system, cause digestive problems, and even lead to high blood pressure, heart attacks and strokes.

So, I recently made the decision that I come to social media for the “social” part of that equation. If I want to watch the news, I will switch on the TV or visit a news website. I no longer need to be hit over the head with it every time I want to chat with my friends.

So, I’m turning off the firehose. I will check the news once or twice a day, and maybe catch the headlines when I’m in the car. But it will be on my terms. I can’t do everything at once. I will also have zero hesitation in blocking anyone who comes to me looking for an argument. Or anyone spouting hateful nonsense. I don’t owe them my attention. Their right to free speech doesn’t negate my right to not listen.

I need to separate time for work and time for home life, and maybe most importantly, time to relax and take care of my mental health.

To this end, I’ve created a variety of Twitter lists, so I get to see only the people I want to keep up with, and I ignore the rest. I barely use Facebook anymore. Instagram is more restful. After all, it’s my time and my experience. I should get to curate my feeds and choose what I want to see.

I’m not advocating living in a bubble, nor am I suggesting we should be passively uninformed about the important issues of the day. I’m just saying we don’t have to be constantly beaten over the head with anxiety inducing headlines, or have to listen to every troll or keyboard-happy jackass on the Internet.
