Chapter 2
How Personal Computing Created the Foundation for Artificial Intelligence
Christmas morning, 1982. I can still remember the weight of the box, the distinctive Sinclair packaging, and the moment I first saw those rubber keys. The ZX Spectrum 16K, with its promise of colour computing. It would change my life, though I couldn't have known it then. I was just a kid who wanted to play games. The universe had other plans.
The Spectrum had launched just eight months earlier, on 23 April 1982, at a price of £125 for the 16K model. By Christmas, demand was so high that Sinclair Research was "notoriously late" in delivering to eager customers. Those of us lucky enough to unwrap one that morning were among the first wave of what would become a computing revolution.
Across Britain, similar scenes were playing out in thousands of homes. We were unwitting participants in the first act of a revolution that would ultimately enable machines to think. But on that Christmas morning, all I cared about was getting the thing connected to the family television and loading my first game.
The ritual of loading games from cassette tape would become burned into the muscle memory of our generation. Type LOAD "", press play on the tape recorder, and wait. The screech and warble of data loading became the soundtrack of patience. Sometimes it worked first time.
Often it didn't. "R Tape loading error" – the most frustrating phrase in the English language. But when it worked, when Manic Miner or Jet Set Willy finally burst into life in all its 15-colour glory, the wait was forgotten.
Those rubber keys, described by users as offering the feel of "dead flesh", became an extension of my fingers. Each press had to be deliberate, considered. This wasn't typing; it was programming. And programming, I discovered, was magic. You could type words that became actions. You could create something from nothing. You could tell this machine what to do, and it would do it – mostly.
The country was undergoing a peculiar transformation in those years. While traditional industries collapsed and unemployment soared past three million, while miners prepared for strikes and factories closed their gates forever, a new economy was being born in bedrooms and back rooms, on kitchen tables and in garden sheds. We didn't know we were part of it. We were just kids with computers, but collectively we were learning skills that would define the next century.
The Analytical Engine's design anticipated virtually every major feature of modern computers. It had conditional branching - the ability to make decisions based on previous results. It could loop, repeating operations until certain conditions were met. It separated the processing unit from memory, allowing the same data to be used in multiple calculations. Most remarkably, it was programmable. By changing the cards, you could make the same machine solve entirely different problems.
At school, I encountered a different beast – the BBC Micro. These beige boxes, solid and serious, sat in the new computer room like monuments to the future. Where the Spectrum felt personal and playful, the BBC Micro was institutional and important. The keyboards were proper keyboards with real keys that clicked satisfyingly. The commands were different too – instead of the Spectrum's peculiar syntax, the BBC spoke in a more formal dialect of BASIC.
The BBC had launched its Computer Literacy Project in 1982 with extraordinary ambition. They didn't just want to report on the computer revolution; they wanted to create a digitally literate nation. The BBC Micro, designed specifically for the project, was a serious machine costing £400 – more than many families' monthly income. But the message was clear: computers weren't toys or curiosities. They were the future, and Britain needed to be ready.
Our teachers, however, were largely unprepared. I remember Mr. Patterson, our mathematics teacher, approaching the BBC Micro as if it might bite. He'd been teaching for thirty years using chalk and blackboards, and now he was expected to integrate this beige box into his lessons. The few teachers who embraced the technology often found themselves isolated, their innovations unsupported by colleagues who viewed computers with suspicion or fear.
But in the playground and after school, those of us who had computers at home formed informal networks. We swapped games recorded on C90 cassettes, shared programming tips, and pushed the boundaries of what these machines could do. The constraints bred creativity – when you only had 16 kilobytes of memory, every byte mattered. When your graphics were limited to 256x192 pixels in 15 colours, you learned to suggest rather than show. These limitations, frustrating at the time, taught us efficiency and elegance that would serve us well in years to come.
By 1985, 13% of households owned a home computer in the UK, compared to 8.2% of American households in 1984. This wasn't Silicon Valley venture capital driving innovation. This was hire purchase agreements and Christmas savings clubs, parents who didn't understand these machines but sensed they were important for their children's futures.
The geography mattered. This wasn't California with its sunshine and Stanford graduates. This was Britain, where bedroom programmers worked in terraced houses and council flats. Matthew Smith created Manic Miner in his bedroom in Wallasey. The Darling brothers founded Codemasters in their Warwickshire farmhouse. The drizzle outside made staying in to program more appealing. The lack of venture capital meant bootstrapping and creativity. The result was a distinctive British approach to software – quirky, innovative, and often subversive.
By the late 1980s, I had outgrown my Spectrum. The Atari ST 1040 that replaced it was a revelation. Where the Spectrum had 16 kilobytes of memory, the ST had a full megabyte – hence the 1040 designation. It had a proper graphical interface with windows and a mouse, years before Windows became standard on PCs. It had MIDI ports built in, making it the choice of musicians and producers. But most importantly for me, it had proper development tools.
I spent countless hours learning to program the ST properly. Not just BASIC anymore, but assembly language, C, and the intricacies of the GEM operating system. The bedroom programmer era was evolving into something more sophisticated. We weren't just making simple games anymore; we were creating utilities, creative tools, experiments in what was possible.
The breakthrough came when magazine publishers started including coverdisks with each issue. Future Publishing had pioneered this with Amstrad Action issue 4 in Christmas 1985, but by the time ST Format launched in August 1989, coverdisks were standard. These 3.5-inch floppies could hold 720 kilobytes of data – an enormous amount compared to cassette tapes. The magazines were hungry for content to fill these disks, and suddenly bedroom programmers had a distribution channel that could reach thousands.
When my software was selected for inclusion on a magazine coverdisk, it felt like graduation. No longer just programming for myself or friends, but creating something that would be used by strangers across the country. The covering letter from the magazine, the small cheque for publication rights, the credit in the magazine – these were validation that computing could be more than a hobby.
But the real transformation was happening beneath the surface. Throughout the country, a generation was learning to think computationally. We were discovering that problems could be broken down into logical steps, that complex behaviours emerged from simple rules, that machines could be tools for thought, not just calculation. These lessons, learned through trial and error in our bedrooms, would prove more valuable than anything we were taught in formal education.
Yet even as we typed away on our Spectrums and BBC Micros, a different revolution was beginning. In 1989, I got my first taste of online communication through CompuServe. The process was arcane – configuring the modem, dialling the access number, waiting for the connection. Speeds were glacial by today's standards. My first modem ran at 2400 baud. At that speed, you could transmit about 240 characters per second – roughly two tweets' worth of data.
CompuServe was a different world from the internet we know today. It was a walled garden with its own forums, email system, and file libraries. But it was my first experience of communicating electronically with people beyond my immediate circle. The hourly charges were steep – more than £10 per hour in the early days – so sessions were brief and purposeful. You logged on, grabbed your messages, posted replies, and got off quickly.
The modem sounds became the soundtrack of this era. First the dial tone, then the touch-tone beeps as the number was dialled, then that distinctive negotiation sequence – the hissing, screeching, warbling sounds of two modems finding common ground. We learned to interpret these sounds. A clean connection sounded different from a noisy line that would lead to errors and disconnections.
Alongside the commercial services, bulletin board systems (BBSs) flourished. These were individual computers, often run from someone's spare bedroom, that you could dial into directly. Each BBS had its own character, its own community, its own collection of files and messages. You'd build up a collection of phone numbers for different boards, each serving different interests. CIX (Compulink Information eXchange) provided another route to online communication in the UK, alongside the American-dominated CompuServe.
By 1990, during my A Level Computer Science, I encountered something revolutionary – the World Wide Web. Through our college's JANET connection, we could access this new system that Tim Berners-Lee had invented at CERN in 1989. JANET had been operational since 1984, initially running on X.25 protocols at 9.6 kilobits per second, connecting the UK's universities and research councils. By 1991, it had adopted Internet Protocol, opening up access to the growing global internet.
Those first web pages were nothing like today's multimedia experiences. They were simple text with blue underlined hyperlinks. No images, no videos, no JavaScript. Just information connected to other information. But the potential was immediately obvious. Here was a way to share knowledge globally, instantly, without the gatekeepers of traditional publishing.
The transformation accelerated when these islands of computing power started connecting. Tim Berners-Lee's invention wasn't just a technical achievement; it was a philosophical revolution. His vision was modest: a way for physicists to share research papers. He couldn't have imagined that within a decade, his invention would reshape commerce, communication, and human knowledge itself.
In Britain, the academic network JANET was already connecting universities, but it was the web that made networking comprehensible to ordinary people. The same feeling I'd had when I first programmed the Spectrum, but magnified a thousandfold. We weren't just commanding our own machines anymore; we were part of a global network of minds and machines.
In 1993, I found myself at Ouachita Baptist University in Arkansas. Here, I experienced ARPANET for the first time, mainly using it to communicate with home via email. The contrast with what was available back home was stark. While American universities had high-speed connections, UK home users were still relying on dial-up modems and expensive per-minute charges.
I built a PC in my university dorm room – MS-DOS and Windows came on floppy disks, not CD-ROMs. Access to a computer became essential for me from about 1993 onwards. The transition from the Atari ST to PC marked a shift from hobbyist to professional computing.
By 1995, I'd graduated and taken my first job, transitioning to the Macintosh. The CD-ROM had become available by then, transforming software distribution. No more swapping dozens of floppy disks – entire applications came on a single disc.
The World Wide Web was beginning to take shape as something more than an academic curiosity. In 1996, I was hand-coding websites using nothing more than Notepad. Every HTML tag typed manually, every link checked and rechecked. The early web was entirely static – no databases, no dynamic content, no content management systems. Just HTML files sitting on servers, linked together with those distinctive blue hyperlinks.
The process was laborious but strangely satisfying. You'd write your HTML, save it, open it in Netscape Navigator to check it worked, then upload it to the server via FTP. There were basic HTML editors emerging, but their results were unimpressive. Hand-coding gave you complete control, even if it took longer.
Speeds were still painfully slow. A typical dial-up connection ran at 28.8k or 33.6k if you were lucky. Downloading a single high-resolution image could take minutes. This forced a discipline in web design that we've largely lost. Every byte mattered. Images were optimised to the smallest possible size. Designs were clean and simple not by aesthetic choice but by necessity.
The commercialisation of the internet happened with stunning speed. In 1993, there were 130 websites in the entire world. By 1995, there were 23,500. By 2000, there were over 17 million. The transformation wasn't just technological but social and economic. Suddenly, anyone with an idea and basic HTML knowledge could start a business. The barriers to entry that had protected established companies for decades were crumbling.
By 1998, I could see that the internet was going to transform business, but most companies didn't understand what it meant. They knew they needed "to be online" but had no conception of what that actually entailed. Many were being ripped off by companies selling inappropriate solutions. This led me to found the Digital Architecture Group, specifically to help companies understand what the Internet meant for them and how to embrace it.
The parallels with today's AI revolution are striking. Just as companies in 1998 knew they needed to "get on the internet" without understanding what that meant, today's organisations know they need "AI" without grasping the implications. The same pattern of confusion, the same vulnerability to those selling solutions without understanding, the same transformative potential waiting to be unlocked by those who truly understand the technology.
The emergence of Google was a turning point. Before then, search engines were clunky and inaccurate – and extremely slow. AltaVista, Lycos, and Yahoo! (originally a hand-curated directory) gave way to Google in 1998. Google's clean interface and superior results – based on their innovative PageRank algorithm – quickly made it the search engine of choice. This was a crucial development. As the web grew exponentially, finding information became as important as publishing it.
The browser wars marked a specific period in time that would fundamentally shape the modern web. Netscape Navigator dominated initially – at its peak holding over 90% market share in the mid-1990s. But Microsoft's Internet Explorer, bundled with Windows 95, began its assault on the market. By 1998, when I was founding Digital Architecture Group, the battle was in full swing. AOL acquired Netscape for $4.2 billion in November that year, but it was already losing ground. By 2008, AOL finally discontinued support for Netscape Navigator, marking the end of an era.
Each browser had its own quirks, its own interpretation of HTML standards. Internet Explorer added proprietary extensions – ActiveX controls, non-standard CSS properties, its own JavaScript implementations. Netscape had its own proprietary tags. Creating a website that worked correctly in both was a constant challenge. It was a horrible mess. We had to write different code for different audiences, using browser detection scripts to serve appropriate versions. Conditional comments for IE became a necessary evil: "<!--[if IE 6]>" littered our code.
The ecosystems that emerged were basically Microsoft with its proprietary extensions versus everyone else trying to follow standards. Microsoft's dominance meant many corporate intranets were built specifically for IE, creating lock-in that persists to this day. This split would have profound implications for web development for decades to come.
Safari arrived in 2003, released exclusively for Macintosh computers. Apple wanted control over the browser experience on their platform, moving away from their previous reliance on Internet Explorer for Mac. Safari's WebKit rendering engine would later become the foundation for mobile browsing when the iPhone launched.
Firefox emerged from the ashes of Netscape in 2004. Built by the Mozilla Foundation using the open-source Gecko engine, it represented the standards-compliant alternative to Internet Explorer's dominance. For a few years, Firefox gained significant market share, championing web standards and developer tools.
Then in September 2008, Google released Chrome, and everything changed again. Built on the open-source Chromium project, Chrome was fast, simple, and secure. Its V8 JavaScript engine was revolutionary, enabling the complex web applications we take for granted today. Chrome's rapid release cycle and automatic updates meant users always had the latest features and security patches. Within a few years, it overtook both Internet Explorer and Firefox to become the dominant browser, a position it still holds today with over 65% market share globally.
Connection speeds were gradually increasing throughout this period. We progressed from 28.8k and 33.6k modems to 56k (though you rarely achieved the theoretical maximum). ISDN offered 64k or 128k for those who could afford it. When broadband finally arrived in the UK in 2000, it promised "always-on" connectivity – no more dialling up, no more engaged tones, no more per-minute charges. The initial 512k ADSL connections seemed impossibly fast compared to dial-up.
But the digital divide persisted. Even today, there are still cold spots in the UK that cannot achieve more than 1Mbps. Rural areas, particularly in Scotland, Wales, and Northern England, struggle with connectivity that urban dwellers take for granted. This disparity affects everything from education to business opportunities, creating a two-speed digital economy.
Commercial pressures throughout this period profoundly influenced the modern web. The browser became the battleground for control of the internet experience. Microsoft saw it as a threat to Windows and tried to subsume it. Google saw it as the gateway to their services and advertising empire. Apple saw it as part of their integrated ecosystem. These competing visions shaped not just browsers but the entire web platform.
The dot-com boom felt different in Britain than the frenzy reported from Silicon Valley. We read about venture capital flooding into American startups, but the UK scene was more cautious, more traditional. Boo.com, launched in 1998 by Swedish entrepreneurs but headquartered in London, became our most visible example of dot-com ambition. They promised to revolutionise fashion retail with 3D product views and same-day delivery. They raised £80 million before selling a single item.
In London's Shoreditch, warehouses that had stood empty since the 1970s were being converted into offices for new technology companies. The atmosphere was electric but distinctly British – less talk of "changing the world" and more focus on finding sustainable business models. Still, the language of Silicon Valley was creeping in – "disrupting" industries, "pivoting" strategies, "scaling" operations.
The crash, when it came in March 2000, affected markets globally. While American indices like the NASDAQ grabbed headlines with their 78% fall, Britain had its own reckoning. The FTSE techMARK index fell 75%. Lastminute.com, which had floated at 380p per share amid massive hype, fell to 20p. Boo.com collapsed in May 2000, becoming the poster child for dot-com excess.
The founders had spent £600,000 on a launch party at Café Royal but had fundamental problems with their technology – the site was so advanced it took eight minutes to load on a typical home connection.
But something important survived the wreckage. The infrastructure built during the boom years remained – the broadband networks, the server farms, the payment systems. More importantly, the crash had taught valuable lessons. The internet was brilliant for connecting people and sharing information, but it couldn't magically transform bad business models into good ones.
E-commerce platforms like Amazon had emerged, though I didn't discover Amazon until 2008. The cloud computing revolution was beginning to take shape. These cycles – e-commerce dominated by Amazon, cloud computing dominated by a few major platforms – would repeat with AI. We've seen all this before, which is why this historical context is so important.
Then came September 11th, 2001. Beyond the human tragedy, the attacks fundamentally altered how we thought about digital systems. The same networks that enabled global collaboration could coordinate terror. The openness that had defined the internet's growth suddenly looked like vulnerability. In Britain, the Regulation of Investigatory Powers Act 2000 was expanded. Every internet service provider was required to install equipment enabling government monitoring. The dream of an open, decentralised internet was being replaced by something more controlled, more surveilled, more corporate.
Throughout these upheavals, one constant remained: Moore's Law. Gordon Moore's 1965 observation that the number of transistors on a microchip doubled roughly every two years had held remarkably true. A computer purchased in 2000 would be effectively obsolete by 2004. This relentless improvement was creating new challenges. Computational power was growing faster than our ability to use it meaningfully.
The transformation accelerated with social media. Friends Reunited, launched in 2000 by Julie and Steve Pankhurst from Barnet, had connected 15 million Britons with old school friends. But when Facebook arrived in British universities in 2005, it offered something different: continuous connection rather than nostalgic reunion. Within months, everyone was on it.
People started living their lives as if they were always being watched, because in a sense, they were. Every party, every relationship, every thought became potential content.
By 2007, Facebook was processing 25 terabytes of data per day – roughly equivalent to the entire printed collection of the Library of Congress. But Facebook was just one source. Google was indexing billions of web pages. Amazon was tracking every click. Mobile phones, increasingly smart, were recording location, movement, communication patterns. Humanity was creating a digital shadow of itself, a vast corpus of behavioural data waiting to be understood.
The challenge was that traditional computing couldn't make sense of it all. You could store the data, retrieve specific pieces, but finding patterns, understanding meanings, predicting behaviours – that required something new. We needed machines that could learn from the data itself, that could find patterns no human would ever spot.
The stage was set for a new revolution. The infrastructure was in place – powerful computers, global networks, vast data repositories. The need was clear – systems that could find meaning in complexity, learn from experience, make decisions based on patterns too subtle for human perception. The computational power that had been growing exponentially for decades finally had a purpose worthy of its potential.
Looking back now, the thread from that Christmas morning in 1982 to the dawn of artificial intelligence seems almost inevitable. But it wasn't. It was the result of millions of individual decisions, of bedroom programmers pushing boundaries, of teachers struggling with new technology, of entrepreneurs risking everything on half-understood possibilities.
That 16K Spectrum, which I still have, represents more than nostalgia. It's a reminder of when computing was personal, when every byte mattered, when programming meant understanding the machine intimately. The progression from typing LOAD "" to building websites by hand to wrestling with big data and artificial intelligence wasn't just my journey – it was humanity's journey, compressed into a single lifetime.
We'd spent thirty years teaching machines to calculate. We'd spent another decade teaching them to communicate. The question now was: could we teach them to think? The answer to that question would reshape not just technology but society itself. The digital revolution had built the infrastructure. The data explosion had provided the raw material. Now artificial intelligence would transform what was possible.
But that transformation, from digital revolution to intelligence explosion, is a story for the next chapter.
