We live in a time that most people call the Fourth Industrial Revolution (4IR). It is the “age of the smart machine”. Every aspect of our lives is supposed to be transformed, as we get plugged into the ubiquitous, electronic, networked, computerised, information-driven, global universe. Soon, our biological selves are supposed to mesh with our digital selves, so that we become what Ray Kurzweil calls technological singularity.
Remember we are talking here about a revolution, not just a speeding up of the evolution of the computer age, which started around about the end of World War 2.
The first digital computer, which we might call the ABC of computers (the Atanasoff–Berry computer), was invented in Iowa, US, in 1942. The first cyber-system came into being during the war, when Norbert Wiener designed technology to aim and fire anti-aircraft guns automatically. He specified it (and named it) in 1948 in his famous book, Cybernetics.
Artificial intelligence (AI) got going with the Turing machine — which was not a machine, but a mathematical model, or algorithm — in 1950. By then, the computer age was fully under way. The internet appeared in 1969, linking computers at various universities via standard telephone lines. At almost the same time, two computers — one at Stanford and one at UCLA — connected for the first time via satellite, making the first move towards what would become the world-wide-web (or simply, the Web). Digitised, networked computer technology has continued to evolve, more and more quickly, ever since.
However, researchers of various kinds (scientists, social scientists, historians of technology) are realising more and more that there is not much of a revolution in the “4IR”.
Despite all the hype pumped out by organisations like the World Economic Forum, there is not really any fundamental social and political change associated with the evolution of information and communication technologies.
It is easy to imagine a prize-winning robot proclaiming that she wants to end poverty and achieve world peace — perhaps Siri saying this as she exits our iPhones into her much more mobile bionic body; or a self-driving Uber vehicle being able to “read” the intentions of a Joburg taxi driver like a smart (human) Mzansi driver can. But we are light years away from anything like this, if ever it comes about.
The Turing machine suggested to us in 1950 that these kinds of computers are probably impossible in principle, and we know now that robots — for all their positional accuracy, and dexterity, and ability to work for long hours without pay — are not capable of common sense.
Advocates of the “4IR” have their work cut out to keep us all convinced. They do so by continually trotting out lists of the allegedly magical, transformative “technologies” that supposedly prove the existence of the 4IR. There’s a kind of formula that they apply, which goes something like this:
- List between seven and 15 digital technologies that sound smart, make us feel outdated and leave us in awe of the future;
- Even if they are not of the 21st century, declare them to be so;
- Declare that there is amazing, unprecedented convergence between them; and
- Suggest that they produce changes that will disrupt and transform every part of our lives.
The list that they come up with usually includes the following popular “technologies”: artificial intelligence (AI), robots, machine learning, the internet of things (IoT), cyber-physical systems, 3D printing and blockchain. Yes, there’s blockchain!
What on earth is blockchain doing on this list? Blockchain is really boring.
The others are not boring. AI is about the digital brains that run in intelligent machines. No matter what generation we come from, there is remembered delight at the idea of AI — Isaac Asimov’s three laws of robotics, “Star Wars”, your robopet Poo-Chi, “Black Panther”, all cool stuff.
Or there is Siri in your phone, knowing just about anything, and soothing tired male souls. And other robots? Well, a lot of us are scared that the robots are coming for our jobs. Still, one only has to think of popular robotic movie heroes to realise how important the idea of robots is for those trying to mobilise us to join the 4IR.
Machine intelligence is what makes robots cool. The thinking, talking, walking, running, jumping, feeling machine is what the hype is all about.
The IoT is about dreams of ultimate comfort. Everything in our world is connected in our service. The proverbial case is the digital alarm clock that wakes you up, switches on the coffee machine, runs a hot bath, checks the weather for the day and suggests an outfit from an inventory of clean clothes while simultaneously checking traffic patterns and planning your best route to work, also reminding you of your appointments for the morning, booting up your favourite soundtracks to soothe you awake, prompting you to use your cellphone to choose your breakfast menu for the day, and letting your hard-working, early-rising maid in the kitchen know what she should start cooking, all connected via the internet. Networks and devices and data that we are deeply interested in.
Cyber-physical systems are next-generation IoTs, with even more clever AI that runs all the connections between things. But the language itself, “cyber-physical”, is enough to keep us interested when the 4IR prophets come around.
Even 3D printing is cool. I remember my daughter, on first hearing about it: “so it’s like, Princess Leia or Obi-Wan Kenobi being printed in 3D in front of us, I want one!” She was thinking 3D holograms, but that’s the fantasy that draws us to the idea. Even the real thing is cool — have you ever watched them
printing a 3D baby?
But blockchain is boring. It is boring like accountancy is boring. An accountant is a woman or a man in a grey suit who does calculations and stores things in files. Blockchain is a database in a grey suit that does calculations and stores things in files. It stores information digitally, but differs from past databases (vague interest aroused?) in that it structures information in discrete “blocks” rather than in tables. These blocks are closed when filled, and linked in a chain that constitutes a secure, shared, distributed ledger. The sequence of each block is irreversible — it is given an exact timestamp and a hash (a digital fingerprint or unique identifier).
You see what I mean, blockchain is boring? It has none of the hype and excitement associated with it that the robots and stuff do.
