New Technologies in the Early Internet Era Dramatically Changed How We Live and Communicate

The arrival of new technologies in the early days of the internet dramatically changed the way we live and communicate. The age of information that updates automatically without page refreshes, the emergence of asynchronous JavaScript (Ajax) — it was truly revolutionary. The moment that a single button click could exchange information with a server. Many people remember the excitement of sensing the possibilities in that instant. This article traces the lineage from Digg's voting button culture — one of the prototypes that eventually became the "Like button" and social media reaction features — to the transformation of consumer experience brought about by today's AI technology, and the emerging trends in new product design. It presents the lived experiences and thought processes of veteran practitioners in full — including stories of how Ajax's groundbreaking "click and the number changes" experience sparked imitation and idea-sharing in early product development, how "likes" as emotional feedback on social media and the web began to influence algorithms and surface user preferences, and how modern AI tools and creativity enhancement practices like ketone drink routines all connect. How is history fusing with modern technology and new challenges for the future?

By reading this article, you'll come away with a tangible sense of the deep relationship between technology and consumer psychology, and how novel ideas take shape in the real world. The key to opening the door to the future lies in learning from past innovations and incorporating new sensibilities. Let's explore the evolution of the "Like button" and the consumer experiences that are ahead of the AI era.

The Ajax Revolution and the Impact of "Instant Click Response"

In the early 2000s, the web consisted largely of static pages of information. Forced to reload pages repeatedly, there came an innovative experiment that marked a turning point — transforming both technology and user experience. With the arrival of Ajax technology, a groundbreaking experience for its time was realized: information updated with a single click, no page reload required.

Furthermore, the engineers of that era began to realize that with this new technology, even casual interactions could become part of a much larger algorithm that would influence consumer experience. By making content ratings visible as numbers — forming a feedback loop — information matching users' interests would be served back to them, progressively personalizing the flow of information across the web. The key points were:

  • The introduction of Ajax technology created the experience of numbers updating instantly with a single button click
  • The "Digg button" served as a simple means by which users could signal their interest in or agreement with content

Similar mechanisms began to appear around this time, with developers devising ways to protect their own ideas. The social value of a small click resonated with many people, gradually solidifying the path toward becoming the core system of enormous social platforms.

As time passed, the concept of the "Like button" — or "Digg button" — evolved beyond being a mere reaction button. It became an emotional feedback mechanism that influenced the quality of communication and the trust between users. Through this mechanism, the modern consumer experience took shape: how easily and reliably our digital "empathy" and "evaluations" are recorded, and how algorithms continuously deliver new information based on them.

What must be noted, however, is not simply how far the technology has advanced, but also the resulting changes in human emotion and behavior — and the aspects of those changes that generate debate. In the early days, the simple thrill of an "easy-to-press button" coexisted with user conflicts of opinion and extreme reactions to certain content. For example, the ability to upvote and downvote comments — intended to encourage constructive discussion — sometimes had the side effect of "amplifying only the negative." These experiences, alongside the rapid pace of technological advancement, highlighted the difficulty of balancing emotional dynamics and achieving social consensus among users.

Developers also found themselves compelled to obsess over the details of product design as they conceived new mechanisms — a process that itself was a continuous series of playful experiments and trial and error. Small experiments initially conducted to validate concepts gradually grew into major movements that spread across the entire market, ultimately embedding the universal feature of the "Like button" into people's daily lives. The journey from the Ajax revolution to the birth of the Digg button is not merely a story of one technology's success; it is a valuable historical case study showing how the fusion of emotion and technology comes to determine the shape of future consumer experience.

Behind the Birth of the Like Button and AI-Extended User Experience

As technology evolves, product builders in the field are constantly exploring new user experiences. And the advance of modern AI has shifted toward innovative product design that incorporates not just "ease of use" — but emotions and even physical responses. Just as the ketone drink episode illustrates, the focus is now on how to design products in environments where diverse senses — voice, video, touch — work in combination, delivering fresh experiences to users.

Kevin Rose mentioned that he mixes ketone drinks into his coffee to help with focus. This was introduced not as promotion for any specific product, but as "a personal habit for maintaining creativity."

This anecdote is framed not as a pursuit of health or efficiency per se, but as a practical example of what measures he takes to keep his thinking in peak condition. The important point is less the act of using a ketone drink and more the broader context: the value of having deliberate practices to improve the quality of one's concentration.

Technologists and product builders are also seeking novelty in design and interaction in developing AI-powered product tools. In recent years, tools like Vercel's "v0" and "Cursor" have emerged, enabling rapid prototype building with AI. These tools are designed for intuitive use by designers and marketers as well as engineers, providing a new creative environment where "anyone can quickly give form to a product." For instance, the process of photographing a sketch drawn on paper and having an AI generate multiple interface options and design patterns from that image fundamentally overturns previous concepts of product development.

In this kind of product development environment, systems are in place to collect user opinions in real time and immediately reflect feedback into the product. As a result, product improvements that used to be complex and time-consuming can now be completed in minutes — or hours. Investors and builders in the field are convinced that this cycle of rapid development and testing will dramatically advance the overall consumer experience of the future.

AI-driven code generation and design exploration are also evolving. Specifically, processes that automatically generate multiple variations from a single operation — and then compare and evaluate them — are being adopted. Product teams iterate through initial drafts to produce ten, twenty revised variations, steadily approaching the ideal user interface design. This series of trials and experiments is backed by a spirit in which technologists themselves fear failure less and instead embrace the willingness to "put themselves out there" with new ideas.

Behind all of this is the fact that consumers seek not just convenience but emotional satisfaction and surprise. While conventional products tended to emphasize functionality and efficiency, modern users strongly desire experiences that make their hearts quicken — in the process of using a product, and in the feel of the result. For example, rather than a simple "click," visual effects where numbers seem to burst when pressed, or interaction accompanied by audio, give users a new kind of delight, ultimately adding significantly to the perceived value of the product.

Modern product development must pursue the following points:

  • The fusion of technological innovation and design that speaks directly to user emotions
  • Establishment of rapid prototyping and feedback cycles using AI tools
  • Creation of new experiential value in user interfaces
  • Emphasis on learning through fearless challenges and willingness to fail in public

The sequence — from the ritual of drinking a ketone beverage to the diverse design exploration enabled by AI — is truly symbolic of future product development. Product builders today are not afraid of today's failures and experiments; they burn with passion for continuously refining the user experience in new ways. This spirit will drive the entire product market going forward, ultimately becoming the engine for innovative change across our lives and society as a whole.

AI and Privacy Reshaping the "Next-Generation Interface"

The transformation of consumer interfaces brought about by modern technological evolution is not limited to improvements in operability. We are entering an era where our lives are significantly shaped by what information is recorded, how it is managed, and how privacy is protected.

Meetings and personal conversations used to rely heavily on memory, and it was uncommon for people to save important moments in detail. But with the advance of AI technology, technology for recording conversations, converting them to text, and even extracting emotions and themes from that content is advancing rapidly. Some companies are developing systems that use dedicated AI devices to record conversations and, when needed, extract key keywords and emotional tones. This makes it easy to look back on discussion content from meetings and, because the subtle nuances of human relationships are preserved, has the potential to contribute to problem solving and communication improvement.

However, such systems inevitably come with privacy concerns. In an environment where everything is constantly recorded, users must always be conscious of how their words are stored and who can access them. In practice, social debate is active — with some people choosing not to use recording devices in certain situations, out of privacy anxiety. For example, the concern that "we won't be able to speak frankly in systems that record everything at home or at work" is a natural reaction for many users. Yet technologists are also seeking solutions through new product design and user feedback. For instance, experiments have been made with a color-coded recording mode (red = full recording, green = themes only, etc.), giving users the flexibility to switch based on the atmosphere of the moment.

The consumer interface of the future will also play a role not just in recording information, but in enriching emotions and experiences themselves. Just as there have been experiments with conversing with ChatGPT over the phone, voice-mediated AI communication has the potential to go beyond mere mechanical responses and bring users a sense of reassurance and empathy. Furthermore, as "Like" and "Digg" evaluation signals on social media are reflected in algorithms, users encounter content that aligns with their preferences and emotions far more frequently. Behind these mechanisms lies a new form of communication — by which users project their emotions and opinions onto society as a whole — and as a result, a wider diversity of communities and small online circles than ever before has formed.

In this way, the constant recording of information and the questions of privacy, combined with the introduction of new communication patterns, are having a major impact not only on our individual lives but on the transformation of society as a whole. The future in which AI extracts emotions and themes from recorded data and provides optimal, personalized feedback has already begun to emerge as a partial reality. Product builders and investors in the field view these new consumer interfaces as holding enormous potential for improving the overall sense of "connection" and "security" in society.

The reconstruction of information through recording and analysis is also expected to serve as a personal memory aid and as a means of improving the quality of communication. Of course, not everything will proceed smoothly — disputes about privacy protection and the handling of historical records, and other negative aspects, cannot be denied. Even so, technologists are pressing forward to create the future, with both "technological solutions" and "social consensus-building" advancing in tandem — accepting the reality of mixed opinions in full. The modern consumer interface is rooted in a philosophy and human dimension far deeper than simple recognition, and will play an extremely important role in the transformation of society going forward.

Conclusion: Toward a Consumer Experience Where Technology and Emotion Converge

In this article, we have explored how the Ajax revolution gave birth to the "Digg button," how it evolved into the "Like button" to become the foundation of our social media experience, and how modern AI and product design are engaging with user experience and emotion. Technology has always advanced in step with human creativity and emotion, and it is at the extension of that lineage that the new user experience of the AI era exists. The spirit of technologists who continue to embrace new challenges without fear of failure is the driving force that will greatly elevate future development environments and user experiences. Negative feedback and privacy concerns are inevitable elements of that process, but they too are considered part of the unfolding story. We can only look forward to a future in which, having learned from past innovations and incorporated new sensibilities, both technology and society advance in harmony — two wheels turning together.
