Can you say something about some early concept that nobody thought would be important, but turned out to be absolutely crucial to the development of the internet?

Certainly. One early concept that was initially underestimated but turned out to be absolutely crucial to the development of the Internet was the idea of packet switching.
Packet switching is a method of data transmission where information is broken down into smaller units called packets, which are then sent independently across a network and reassembled at their destination. This concept was developed in the early 1960s, primarily by Paul Baran at RAND Corporation in the US and Donald Davies at the National Physical Laboratory in the UK.
When Baran first proposed this idea, it was met with significant skepticism. AT&T, the dominant telecommunications company at the time, dismissed the concept as unfeasible. Many experts believed that a circuit-switched network (like traditional telephone systems) was the only viable way to transmit data reliably.
However, packet switching offered several advantages that would prove crucial for the Internet:
Efficiency: It allows multiple users to share the same data path, making more efficient use of network resources.
Robustness: If part of the network fails or is destroyed, data can still reach its destination by taking alternative routes.
Scalability: It's easier to add new nodes to a packet-switched network without disrupting the entire system.
Cost-effectiveness: It doesn't require a dedicated line for each communication, reducing infrastructure costs.
The ARPANET, the precursor to the Internet, adopted packet switching as its core technology. This decision laid the groundwork for the modern Internet protocol suite (TCP/IP) and enabled the decentralized, resilient network we use today.
It's fascinating to consider that a concept initially dismissed by industry leaders turned out to be the backbone of one of the most transformative technologies in human history. The story of packet switching serves as a reminder of the importance of innovative thinking and the potential for seemingly niche ideas to revolutionize entire fields.
Would you like me to elaborate on any aspect of packet switching or explore other initially underestimated concepts in Internet history?
Certainly. Another initially underestimated concept that became crucial to the development of the Internet was hypertext, particularly as implemented in the World Wide Web.
Hypertext refers to text displayed on a computer or other electronic device with references (hyperlinks) to other text that the reader can immediately access. While the concept of hypertext was proposed by Vannevar Bush as early as 1945 in his essay "As We May Think," it wasn't widely recognized as a transformative idea for information sharing.
Ted Nelson coined the term "hypertext" in the 1960s and worked on a complex system called Project Xanadu. However, his vision was seen as overly ambitious and impractical by many. Even when early hypertext systems were developed in the 1980s, they were often viewed as niche tools for specialized applications rather than a foundation for global information sharing.
The true potential of hypertext was realized when Tim Berners-Lee proposed the World Wide Web in 1989 while working at CERN. His implementation of hypertext was simpler than previous concepts, using:
Initially, many people, including internet pioneers, didn't see the significance of Berners-Lee's proposal. The web was seen as just another Internet application, not fundamentally different from existing tools like Gopher or WAIS.
However, the simplicity and flexibility of the web's hypertext implementation turned out to be its strength. It allowed for easy creation and linking of content, leading to exponential growth in web pages and users. The ability to jump from one piece of information to another related piece anywhere in the world revolutionized how we access and interact with information.
Today, the web's hypertext system forms the basis of our online experience, from social media to e-commerce to online education. What was once seen as a simple tool for sharing research papers at CERN has become the primary interface for accessing the vast resources of the Internet.
This story illustrates how sometimes the most impactful innovations are those that simplify and democratize existing concepts, making them accessible to a wider audience. The underestimation of the web's potential also highlights the difficulty in predicting which technologies will truly change the world.
