ARPANET (1969 – 1990): The beginnings of connectivity
ARPANET, created by the United States Department of Defense, was the first step towards what we know today as the Internet. The main goal of ARPANET was to develop a network capable of connecting users on different computers, facilitating communication and data exchange.
First connections and expansion
The first ARPANET link was established on November 21, 1969 between the University of California at Los Angeles (UCLA) and the Stanford Research Institute. Soon after, the network expanded to include the University of Utah and the University of California at Santa Barbara, marking the beginning of an interconnected network that would allow communication among multiple users.
Rapid growth
In 1971, the network connected 24 computers from various universities and research centers. This number grew rapidly to 213 in 1981 and 500 in 1983, demonstrating exponential growth that laid the foundation for the expansion of the modern Internet. This growth was a clear indication of the potential and need for an interconnected global network.
Key Technologies
ARPANET introduced key communication technologies and protocols that would be fundamental to the later development of the Internet. The most important of these were the Transmission Control Protocol (TCP) and the Internet Protocol (IP). These protocols enabled the reliable transmission and proper routing of data across the network, and became the backbone of the Internet architecture as we know it today.
The creation and expansion of the ARPANET was pivotal in the evolution of global connectivity, laying the technological and conceptual groundwork for the development of future generations of the Internet. Its legacy lives on in the protocols and structures that underpin the Internet today.
Web 1.0 (1990 – 2004): The static Web
In 1990, Tim Berners-Lee developed HTML (HyperText Markup Language), URL (Uniform Resource Locator), and HTTP (HyperText Transfer Protocol), technologies that laid the foundation for the web. These innovations made it possible to create and link documents, providing the structure necessary for online browsing. In 1994, Berners-Lee founded the World Wide Web Consortium (W3C), which established open standards to ensure the interoperability and orderly growth of the internet.
Static pages
Web 1.0 was characterized by static information and a lack of interaction between users and servers. Web pages were static documents that did not allow users to modify their content. The only person who could interact with the webpage was the site administrator, who updated and maintained the content.
Content consumption
In the Web 1.0 era, users were primarily passive consumers of content, similar to reading a magazine or digital newspaper. Web sites provided information in a one-way fashion, with no opportunity for interaction or feedback. Blogs and other forms of user-generated content did not yet exist, limiting active audience participation.
Browsers and search engines
To facilitate browsing and searching for information, tools such as Netscape (1994-2008) and Altavista (1995-2013) emerged. Netscape was one of the first widely used web browsers, allowing users to explore the internet in a more intuitive way. Altavista, one of the first search engines, offered users the ability to find information efficiently, marking a significant advance in the accessibility of online resources.
Web 1.0 was instrumental in creating a global information platform and laying the groundwork for future generations of the web. Although limited in terms of interactivity and user-generated content, this initial phase was crucial to the expansion and popularization of the internet worldwide.
Web 2.0 (2004 – 2017): The interactive web
The advent of Web 2.0 marked a shift toward a more dynamic and participatory Web, where users could interact and create content, revolutionizing the way people use the Internet.
Interactivity and web applications
Web 2.0 introduced interaction tools and web applications that allowed users not only to consume content, but also to create it. Technologies such as AJAX (Asynchronous JavaScript and XML) enabled the creation of faster and more dynamic web applications, improving the user experience and allowing content to be updated without reloading the entire page. This opened the door to a wide range of interactive and collaborative applications.
Social platforms
Social networks such as Facebook, Twitter, YouTube, and Instagram became key platforms in the Web 2.0 era, allowing users to easily share and create content. These platforms fostered online interaction and collaboration, making it easier for people around the world to connect. Two notable developments in 2004, Google’s IPO and the creation of Facebook, accelerated the development and adoption of Web 2.0 and solidified the importance of social networking in everyday life.
Content centralization
Although Web 2.0 has enabled greater user participation in content creation, this content is centralized in technology companies that handle large amounts of personal data, leading to growing concerns about privacy and data control. This centralization has led to debates about the ethics and responsibility of these companies in managing and protecting user information.
Social impact
Web 2.0 has drastically changed the way societies receive and interact with information. It has democratized access to content creation, allowing anyone with an Internet connection to become a creator and distributor of information. It has fostered the emergence of new business models and forms of communication. It has also facilitated social and political movements by providing platforms for organizing and expressing ideas at scale.
Web 2.0, with its emphasis on interactivity and user participation, has transformed the digital landscape and laid the groundwork for an era of unprecedented connectivity and collaboration. Despite the challenges associated with the centralization of content, its impact on society and the way we communicate and share information has been profound and lasting.
Web 3.0 (2017 – ): The decentralized web
Web 3.0, also known as the Decentralized Web, seeks to put users back in control of their data and content through decentralized technologies. This evolution aims to overcome the limitations of Web 2.0 and provide a more secure, private, and user-controlled environment.
Decentralization and independence
Web 3.0 proposes replacing centralized platforms with open protocols and community-managed networks. The use of distributed ledger technologies, such as blockchain, ensures data security and privacy. These decentralized networks eliminate the need for intermediaries and allow direct transactions and communication between users, reducing the risk of censorship and centralized control.
Token economy
One of the distinguishing features of Web 3.0 is the introduction of a token economy, which provides incentives and rewards to users. Cryptocurrencies and non-fungible tokens (NFTs) are examples of this new digital economy. These tokens enable the creation of new business models and forms of economic participation, where users can derive direct benefits from their participation and contribution in the network.
Data ownership
In Web 3.0, users have full control over their data, identity and digital assets. Decentralized platforms allow the creation of digital identities that are secure and controlled by the users themselves. This autonomy in data management contrasts with the centralization of Web 2.0, where large corporations have access to and control over user information.
Technological innovations
Web 3.0 incorporates advanced concepts such as machine learning, artificial intelligence, and the semantic web. These technologies enhance the ability of machines to understand and process information more effectively, enabling more intelligent and personalized interactions. The semantic web, in particular, aims to create an environment in which data is better structured and more accessible to machines, enabling more efficient navigation and information retrieval.
Technologies behind Web 3.0
- Public DLT or blockchain: The distributed ledger technology that underpins cryptocurrencies, ensuring that transactions are transparent, secure, and verifiable without the need for intermediaries.
- Smart Contracts: Self-executing programs in which the terms of the agreement between buyer and seller are written directly into lines of code. They enable secure and automated transactions without the need for intermediaries.
- IPFS (InterPlanetary File System): A protocol and network designed to create a decentralized method of file storage and sharing. IPFS aims to connect all devices to the same file system.

However, innovative solutions are being explored, such as decentralized content moderation mechanisms and decentralized reputation systems, which seek to balance freedom of expression with the need to maintain a safe and ethical online environment.
- Technical complexity: Introduces advanced technologies, such as blockchain and smart contracts, that can be difficult for the average user to understand and use. Unfamiliarity with these technologies can limit their adoption and create a significant barrier to entry for new users.
- Cost and scalability: Web 3.0 transactions can be costly due to associated bandwidth fees. In addition, scalability remains a challenge as current DLTs cannot handle the same number of transactions as centralized solutions, which can lead to congestion and high transaction costs during periods of high demand.
- User interface: The user interfaces of Web 3.0 applications are often not as user-friendly and intuitive. The complexity of the underlying technologies can make it difficult to design accessible interfaces, which can hinder mass adoption of these applications.
- Regulation: The regulation of decentralized technologies is a gray area, with many governments still trying to understand and legislate the use of cryptocurrencies and other Web 3.0 technologies. Lack of regulatory clarity can create uncertainty and slow investment and development in the space.
Notable criticisms
Jack Dorsey, co-founder and former CEO of Twitter, has been outspoken in his criticism of Web 3.0, describing it as a “venture capitalist’s game”. Dorsey argues that instead of democratizing the Internet, Web 3.0 will simply shift power from centralized platforms like Facebook to large investment funds like Andreessen Horowitz. According to Dorsey, this redistribution of power will not benefit ordinary users, but will further consolidate control in the hands of a few powerful financial players.
Elon Musk, CEO of Tesla and SpaceX, has also shown skepticism towards Web 3.0. Musk has suggested that Web 3.0 is more of a “marketing term” than a tangible reality today. In his words, while it is interesting to speculate on what the future will be like in 10, 20 or 30 years, Web 3.0 currently seems to him more of a futuristic idea than a practical reality.
Writer and technologist Robin Sloan has criticized Web 3.0 from a different perspective. Sloan argues that the ability to delete content, an operation he describes as “the antithesis of Web 3.0,” is a desirable quality of Internet services. In his view, the absolute permanence and immutability promoted by Web 3.0 may be more of a disadvantage than an advantage, since the ability to forget and delete is fundamental to the evolution and management of online information.
Conclusion
As we move forward, Web 3.0 promises to further revolutionize our relationship with technology, offering a future where users have greater control over their data and online experiences. Web 3.0, with all its promises and challenges, is an important step toward this ideal future.
A key determinant of success is the evolution of distributed ledger technologies (DLTs), such as blockchain, which must advance significantly to handle the number of transactions required to support this massive project. The scalability and efficiency of DLTs are critical if Web 3.0 is to become a practical and widely adopted reality.
However, Web 3.0 is not without its critics and skeptics. Influential figures such as Jack Dorsey and Elon Musk have expressed doubts about its ability to truly democratize the Internet, suggesting that it may be driven more by marketing than tangible reality. In addition, concerns about the immutability of data and the proliferation of harmful content are challenges that need to be addressed.
Even if Web 3.0 is not fully adopted, we expect tomorrow’s Internet to enhance privacy and provide users with greater security and privacy in their online interactions. The continued evolution of the Web reflects our collective desire for a more open, secure, and fair digital world.
