What is Fauxtomation explained with claims of automation actually done by people, often across the world

Fauxtomation

Writer and filmmaker Astra Taylor explains fauxtomation as "the process that renders invisible human labour to maintain the illusion that machines and systems are smarter than they are." (Faux means false or fake in French). Taylor gives an example of standing in line to collect food and the person in front of her expressing amazement at how the app knew his order was done 20 minutes early. The server replies, "I sent you a message." With the rise in incredible abilities driven by AI chatbots and tools, it's tempting to believe that AI can run anything. But, in many situations, claims of AI magic and sophisticated automation disguise work done by people—often outsourced and poorly paid. An example of fauxtomation is content moderators, whose job is to review and filter objectionable content from the web when the claim is that sophisticated algorithms and AI are doing the work. Other examples are tagging or searching images, transcribing audio, responding to customer queries, making decisions, or, ironically, training machine learning models. In another twist, ordering on the app or touchscreen at McDonalds or the self-checkout at a supermarket, you, as a customer, become the labour of a server or waiter. Some have argued that automation polarises work into vast quantities of small, menial tasks feeding the machines on one end and sophisticated, high-skilled work in designing and maintaining the machines at the other. Amazon has long offered its Mechanical Turk service, which crowdsources assignments with a distributed workforce—they called it artificial, artificial intelligence. The original Mechanical Turk was a hoax from the 1700s where a concealed human chess player fooled onlookers into believing a machine was playing. As a design and UX professional, I've used the Wizard of Oz prototype technique. Named after the infamous wizard secretly controlling impressive machines from behind a curtain, the idea is to give the appearance of a working software prototype by discreetly controlling what people see based on their actions. AI promises instant automation, but that's rarely the case. As you work to automate and remove inefficiencies, it's natural that systems should be supported by people.  Human-augmented work may be a more appropriate term. In many domains, especially where safety is at stake, such as in self-driving cars, reviewing legal documents, or automated background checks, oversight by people may remain critical. Alongside the AI revolution, a quiet revolution nearly as significant for our everyday experience is the tying together of different tools for automation. Tools like Zapier, Google Sheets, Notion, and the growth of APIs allow us to automate workflows across systems, saving massive amounts of time and effort. While the vision of machines reducing our labour persists, history shows that they often drive increased productivity instead of reducing work. This echoes Jevon's paradox, where fuel efficiency gains usually result in increased fuel usage rather than less. I saw an excellent talk by machine learning and AI expert James Smith, in which, before you try machine learning ("I hear you have Magic Pixie dust. Can I have some?"), he would ask, "Have you tried 50 IF statements?" These programmed rules will be more maintainable, less complex, and result in responses that are easy to understand. I learned about fauxtomation from Tom Humberstone's remarkable visual essay What Luddites Can Teach us About Resisting an Automated Future in the MIT Technology Review. Fauxtomation is similar in concept to Potemkin AI, a term from researcher Jathan Sadowski. You can read Astra Taylor's article, The Automation Charade, or watch her discuss fauxtomation at the AI Now 2018 symposium. Sketchplanations continues to be done by me, by hand.

Zigzag trenches in WWI: explaining why trenches were built in zigzags to protect against blasts from artillery and to slow enemies if a trench was attacked or captured

Zigzag trenches

Trench warfare dominated the fighting in WW1. After the initial hasty digging of trenches in the early days of the war, as each side dug in to defend their lines, trenches evolved to be more complex and sophisticated, including digging them in a stepped or zigzag shape. Why were trenches dug in a zigzag pattern? Zigzagging trenches with sharp corners helped remedy several fatal flaws learned from early trench warfare: 1. Zigzags help contain blasts One of the key advantages of a zigzag trench is its ability to contain blasts. In a straight trench, the blast from mortar or artillery fire would travel unimpeded to either side. However, a trench with frequent bends could confine explosions to smaller portions of the trench, reducing casualties. 2. Zigzags help slow an enemy down after capturing a trench A straight trench meant that breaching a portion of it gave a long line of sight and the ability to fire down the trench which could aid attackers. Angles and corners from the zigzag or wavy shape of a trench meant that line of sight was reduced and gave better defensive positions with cover and concealment. So, the simple change from a straight trench to a zigzag gave defenders significant advantages, and both sides used the design during the war. It's painful to imagine the tragic lessons that led to this evolution in design. I learned about zigzag trench design from a children's book about WW1: 50 Things You Should Know About The First World War, by Jim Eldridge. It's striking how such a simple design change can have a significant effect. It's also a great example of how a simple solution can seem so obvious in retrospect and yet may take time to develop. One of the trends of evolution identified in the theory of inventive problem solving that always fascinated me and has myriad applications is how straight lines in products typically evolve to jointed or bent, then wavy lines. As the theory would say, a straight line has unused potential, and someone will find an advantage in introducing a bend or bends. I sketched a similar trend about flat surfaces having unused potential. The Imperial War Museum has a great 9-minute video explaining trench warfare, which discusses the zigzag or stepped design in this sketch.

What is Hanlon's razor example explained: never attribute to malice that which is adequately explained by stupidity. Here, it's explained in a cartoon of someone getting mad at dropped litter when it accidentally was dropped out of the bin bag of another person around the corner

Hanlon's Razor

Hanlon's Razor is the adage: "Never attribute to malice that which is adequately explained by stupidity." Or sometimes, "Never attribute to malice what can be attributed to incompetence." It appears in a similar form by the inimitable Johann Wolfgang von Goethe as, "And I have again observed, my dear friend, in this trifling affair, that misunderstandings and neglect occasion more mischief in the world than even malice and wickedness. At all events, the two latter are of less frequent occurrence," in The Sorrows of Young Werther. The same sentiments are also shared by William James, Churchill, and H.G. Wells. More recently, Douglas Hubbard gave a more modern version in his book The Failure of Risk Management: Why It's Broken and How to Fix It: "Never attribute to malice or stupidity that which can be explained by moderately rational individuals following incentives in a complex system." The mistake of assuming bad intentions was brought home to me when puzzling why people kept leaving paper towels in the sinks of the bathrooms at university. How hard is it to put them in the bin?? A year after assuming my fellow students were either lazy or inconsiderate or both, I was washing my hands when another student dried his hands on the towel, walked to the door, opened it by covering the handle with the paper towel — presumably to avoid the germs — and then aimed his paper towel at the bin which was between the sinks. He missed, and it landed in the sink as he walked off down the corridor. Suddenly, it was clear to me that the hygiene of the door handle was higher in consideration of towel-in-the-sink people than whether or not their towel hit their target (and whether it was worth checking if their towel had hit the bin). It made sense. Someone later moved the bin next to the door, and it didn't happen again. Besides towels in sinks, I've seen people get mad at others pushing in line when the pushers-in didn't realise other people were queuing. I've seen drivers shouting at another driver who's in blissful ignorance of the trouble they've caused. I've seen agents blamed for terrible customer service when the system is at fault, and customer service blame users when the product is at fault. I've seen people despairing at others leaving litter in the park or on the street when animals had dragged out the mess overnight. I've seen people vilified for not moving down on a train when they weren't aware of the squeeze at the other end. And, usually, I think people aren't smart or capable enough, or in fact wicked enough, to carry out the conspiracies that people credit them for. Very often it's the person assuming bad intentions and getting mad who suffers the most. To be sure, there are different degrees of negligence. We can all make mistakes, but if you're doing your taxes, it's not okay to make a mistake because you didn't read the instructions. If you're standing on a busy train, you owe it to others to be aware that you may be blocking an aisle, and we should do our best to make sure our rubbish stays where we put it. But none of us are perfect and so often I think Hanlon's Razor has some truth to it. Perhaps a better formulation of Hanlon's Razor would be, "Before attributing to malice, try attributing to incompetence." But I'm not a fan of the wording with 'stupidity' or 'incompetence'. Awareness is so often the necessary start and what's missing. Since posting this, a few people also shared with me Clarke's Corollary: "Any sufficiently advanced incompetence is indistinguishable from malice." And another relevant name for a similar situation is Cock-up Over Conspiracy. Source for Hanlon's Razor Hanlon's Razor, which encourages us first to consider innocent mistakes rather than assuming ill will, was a submission to Murphy's Law, book two: more reasons why things go wrong, by Arthur Bloch (p52). Murphy's Law is "If anything can go wrong, it will." I've also previously covered Muphry's Law, where, when criticising spelling or grammar, you will make a spelling or grammar mistake yourself.

Kawaii examples - the Japanese culture of cute explained with lots of cute sushi with adorable faces

Kawaii

Kawaii is the word for the Japanese culture of cute, adorable and childlike. When you see a sushi roll with a cute smiley face, that's Kawaii at work. You might also find it in an innocent, high voice like a child's. I love how, by adding a couple of big eyes, maybe with a couple of little highlights, a smiley mouth and perhaps a little shy blushing on the cheek, it's possible to transform a cactus or a pencil case into something adorable. As a family, we've enjoyed the card game Sushi Go, which includes cute wasabi, fried shrimp, and even a chopstick holder. It's a bit like the magic of adding googly eyes to anything to make it fun. The childlike simplicity, sweetness and cute artwork of Kawaii is also in Sanrio's Hello Kitty.

Buoyancy and how ships float explained showing 1m3 of water displaced supporting a tonne of weight and the same principle floating a 50,000 tonne ship

Buoyancy

It’s always been mind-boggling to me how some of the largest and heaviest things we build on Earth are ships that float on water. Cruise ships are like floating towns, some able to accommodate over 5,000 people. How can it be that these gigantic, impossibly heavy objects made of steel can float on water? The key is displacement and realising the considerable weight that the water already supports. In a lake or ocean, each drop of water is supported by the water around it. 1m³ of fresh water weighs 1 metric tonne, which is 1,000 kg. If a ship displaces 1m³ of water, the buoyant force of the surrounding water supports 1 tonne of the ship’s weight. Therefore, a ship weighing 50,000 tonnes will just float if it displaces 50,000m³ of water. Sea water contains salt, which makes it denser than freshwater. As the denser water supports a greater weight, a ship will float slightly higher in salt water than in fresh. The International Load Line, previously called the Plimsoll line, shows how deep a boat sits in the water. To realise the immense power of water, you can try submerging a biscuit tin in a bath. It’ll put up quite a fight. Also see: Plimsoll line Watch out for barnacles Sonic boom Iceberg orientation Siphon

Kitchen table survival skills — skills that keep you out of a scrape in the wild that you can practice at your kitchen table

Kitchen table survival skills

Kitchen table survival skills are survival skills you can put into practice from your kitchen table. I humbly submit my set of tried and tested (and at times learned from bitter experience) non-glamorous, but effective, kitchen table survival skills: Checking the weather There's not always a choice, but having a good handle on the weather (know your clouds) can mean the difference between a nice day out and a disaster. Sensible route planning As Alistair Humphrey's writes in his book Local, "Unfolding a map is the ritual that launches all good journeys." There's art and science in route planning—considering the needs and abilities of your party, the terrain, the effect of the weather or altitude, availability of water, interest and views, access, timing, trail condition and more. So many varied aspects go into it. When planning a family hike now, we weigh up a very different set of factors than we did for two fit twenty-somethings happy to endure a little hardship. Telling someone where you're going If you're going to the wilderness, go with somebody if you can, and leave your intended plan with friends or family back home. If you're not back when expected, at least you'll have someone looking out for you, and a rescue party will know where to start looking. Hiring a guide OK, so it doesn't seem like a survival skill exactly, but going with a local guide will work wonders for your survival. You might not need one for a walk in the local woods, but if you fancy hiking on a glacier or venturing down a river, and it's not something you do too often, then hiring a guide will be the best survival decision you make. Reading up on your route Sure, you can head out and figure it out when you're out there, but mountains, and wilderness generally, are capricious places. There's so much a good hiking book, or a recent trip report can teach you before you set out. Is a river crossable? Is there still snow on a pass? Are the mosquitoes out in force? How long is it likely to take? How much up and down will there be? Where can you camp? And on and on. Taking the right gear Whenever I've been on semi-serious expeditions, I've been very impressed with the kit lists provided by our guides. Every item is carefully chosen—like, say, bringing the 10 essentials—and lists are refined and revisited after each trip. It's rarely exciting assembling your kit and running through lists, but if it means you remembered spare batteries, the water filter, mosquito repellent, or a fire lighter it may prove your saving grace in the wild. More mundane perhaps, but still helpful, is packing your gear in the right places and order in which you'll use it. You're much more likely to stop and put on sun lotion or a warm hat if it isn't stuffed under your sleeping bag in the depths of your backpack. Staying within your limits When we're tired, it's easy to make poor decisions. The best defence I know for this is to plan trips within your limits so you aren't trying to find a camp spot in the dark, feeling too tired to filter the water, or too tired to keep track of where you're going. After a long day, it's easy to start skipping the things that keep us safe, like putting on an extra layer or stopping for water. A guide once told me, "don't be too lazy to be comfortable." Keeping track of time A small, but very useful practice, I've adopted is having a good awareness of time on your excursions. Plan in advance and estimate how long different sections may take. Making a mental note of when you set off from the trailhead or from a rest stop gives you a sense of your progress, lets you know what it might take to get back if you need to, and teaches you how far you might get ahead of you. If your pace is changing, you'll have a good idea of how strong everyone is still feeling. Knowing when the sun rises and sets and how much daylight you have left means you're less likely to find yourselves in the dark without a headlamp. I'm sure you might have more to add to the list. This set came from reflecting on our survival skills before a brilliant chat with Brendan Leonard of the excellent Semi-rad about all things Ultra on the Sketchplanations podcast (episode out in Autumn 2024). Growing up in the 80s, for me survival skills were things Crocodile Dundee had, or perhaps MacGyver. More recently, Bear Grylls would demonstrate making a shelter in the jungle, starting fires, or catching salmon to survive in the wild. However, I realised that my survival skills were much less glamorous, but still rather effective, and most of them are used before I head out on a trip. In other words, my survival skills are ones that mean (touch wood) I don't get into a scrape that need the traditional survival skills most of us think of. As with so much in life, it's often the unglamorous stuff that makes the difference, like showing up every day, replicating before innovating, writing a rubbish first draft, or re-writing. I hope this set may keep your expeditions Type I or Type II fun, rather than Type III.
