A Retrospective: 40 Years of Progress and the Road to Blockchain, AI, and Web3

For today's article I thought I'd step back from Web3 and blockchain and take a trip back in time - and where better to start than the beginnings of my IT career: the 1980s! In fact, my first workplace looked a bit like the computer room pictured above - except that it seemed bigger, and also housed a bank of tape machines and disk drives that looked like top-loading washing machines! A lot has changed since then and your iPhone now possesses significantly more power than that entire room full of machines could muster back then. In fact, over the past four decades, technology has transformed every facet of modern life - reshaping industries, daily habits, and even how society functions.

From room-filling mainframes and the dawn of personal computers in the 1980s to today’s rapidly-evolving world of blockchain, artificial intelligence (AI), and Web3, each decade has introduced foundational innovations and societal shifts. This retrospective examines key stages of technological development, highlights notable successes and failures, and considers the role blockchain, AI, and Web3 may play in the future of IT.

1980s-1990s: The Personal Computer Revolution and Early Networking

The personal computer (PC) revolution began in earnest in the 1980s, as PCs became affordable for home users and businesses alike. This shift empowered individuals to use technology outside the traditional corporate or scientific realms, and major players like IBM and Apple helped make computers household staples. The 1990s then saw the rise of networked computing and the growth of the internet, connecting PCs globally.

Successes: The internet emerged as a critical innovation, linking people, businesses, and information across borders. Companies like Microsoft and Netscape built the tools to navigate this interconnected world, and the dot-com boom in the late 1990s helped propel digital businesses into new economic territory - Amazon being a notable success story.

Failures: The dot-com bubble of the late 1990s is a notable failure, where speculative investment led to overvaluation and the eventual crash of numerous internet startups. Many companies with limited business plans failed, but the underlying internet infrastructure laid a foundation for the future, and only a few gems emerged as the dust settled.

2000s: The Mobile and Cloud Era

The 2000s were defined by mobility and cloud computing. The introduction of smartphones, particularly with the launch of Apple’s iPhone in 2007, made computing portable and accessible. Meanwhile, cloud computing, led by pioneers like Amazon Web Services (AWS), revolutionised how businesses stored, processed, and accessed data by offering scalable infrastructure on demand.

Successes: Cloud services allowed companies to build applications without investing heavily in physical infrastructure. Major platforms like Google, AWS, and Microsoft Azure transformed enterprise IT, providing businesses with scalable solutions and fuelling the growth of tech startups.

Failures: Certain sectors, including traditional data storage and hardware vendors, struggled to adapt to the cloud era. The mobile space also saw its share of failures, with companies like BlackBerry failing to innovate as Android and iOS rose to dominance. The hardware-focused models of earlier mobile companies could not compete in a software-first ecosystem.?

2010s: The Rise of Big Data, Bitcoin, AI, and the Sharing Economy

The 2010s marked the beginning of the big data era, where businesses leveraged data analytics to gain insights into consumer behaviour and improve decision-making. Advances in AI enabled early applications of machine learning (ML) and natural language processing (NLP). Bitcoin, introduced in 2009, began to gain traction in this decade, marking the dawn of blockchain as a significant technological innovation. The sharing economy, with platforms like Uber and Airbnb, further disrupted traditional business models.

Successes: The application of big data and AI transformed fields like healthcare, e-commerce, and social media. Tech giants like Amazon, Google, and Facebook used data to personalise user experiences and drive growth. Meanwhile, Bitcoin’s growing popularity led to the birth of the cryptocurrency industry, which paved the way for decentralised finance (DeFi) and tokenised digital assets.?

Failures: The increased centralisation of user data led to privacy concerns, with notable breaches and scandals like Cambridge Analytica. Bitcoin, while groundbreaking, faced criticism for its energy-intensive mining process and extreme price volatility. Additionally, many startups in the sharing economy faced regulatory issues and ethical concerns, with some struggling to achieve long-term profitability.

2020s: Blockchain, AI, and Web3 – The Future of Decentralisation and Intelligent Systems

Entering the 2020s, we find ourselves on the cusp of blockchain, AI, and Web3. Blockchain promises to decentralise data control, giving users ownership of digital assets through decentralised finance (DeFi) and non-fungible tokens (NFTs). The Web3 paradigm seeks to transform the internet from a centralised, platform-driven model into a user-centric ecosystem built on blockchain technology. Meanwhile, AI continues to evolve, with large language models like GPT-4 introducing new capabilities for natural language processing and automation.

Use Cases in Development:

1. DeFi and Decentralised Applications (dApps): Platforms like Ethereum and Polygon have developed ecosystems for financial services outside of traditional banking. DeFi applications aim to democratise finance, but the field remains highly experimental and volatile.

2. Digital Identity and Data Privacy: Blockchain-based solutions, such as Internet Identity on platforms like ICP, aim to give users control over their data, reducing dependence on third-party authentication services like Google or Facebook.

3. AI and Automation in Blockchain: AI models are increasingly being integrated with blockchain, providing new ways to automate smart contract functionality, analyse market trends, and improve decision-making in decentralised networks.

Challenges:

Blockchain and Web3 face challenges similar to those of early internet and cloud technologies, including scalability, regulation, and user adoption. Additionally, the sustainability concerns around energy-intensive proof-of-work blockchains have been a hurdle, though newer proof-of-stake models like Ethereum 2.0 are helping to address these issues.

Future Potential:

The journey from PC adoption to the current blockchain and AI developments has shown that widespread technological shifts take time. As I covered in last week's article, experts predict it could take 5-10 years for a handful of blockchains to emerge as foundational infrastructures, while AI’s potential continues to grow in fields like healthcare, education, and logistics.

Conclusion: The Future Role of Blockchain, AI, and Web3 in IT

Looking back, each decade has brought transformative technologies that initially faced skepticism but later reshaped the landscape. Blockchain, AI, and Web3 now stand at a similar crossroads. If successful, they could represent the next foundational layer of the internet and IT.

Blockchain and Web3 promise a future where users retain control of their data and assets, which could create more transparent and equitable internet ecosystems. Successful applications of DeFi, digital identity, and tokenised assets could lay the groundwork for a truly decentralised internet.

AI will likely continue to influence nearly every sector, augmenting human capabilities with intelligent decision-making, predictive analytics, and automation. Integrated with blockchain, AI could enable more efficient and adaptive decentralised networks, powering autonomous organisations and complex digital ecosystems.

Just as PCs, the internet, mobile, and cloud computing became cornerstones of modern technology, blockchain, AI, and Web3 promise to transform the way we interact with digital environments. Over the coming years, these technologies may not only redefine the internet but create a decentralised, user-focused world where individuals have greater agency over their data, identity, and digital assets.
