For decades, user experience (UX) and user interface (UI) design have served as the critical layers between human beings and digital systems. The rise of graphical user interfaces, mobile-first design, responsive web applications, and human-centered design methodologies elevated UX to one of the most influential professions in technology. Companies invested billions in research, usability testing, design thinking workshops, and iterative prototyping because the effectiveness of software adoption often hinged on the quality of its user experience.

However, we now stand at the edge of a profound transition. AI agents are no longer just assistive layers operating behind user interfaces. They are becoming the primary navigators of software and systems. Whether embedded into enterprise workflows, consumer devices, or industrial automation, AI agents increasingly perform the interpretive and operational roles that humans once executed directly through interfaces. This shift raises a provocative question: if agents interact with software on behalf of users, what becomes of the UX profession?

Here we examine the traditional role of UX, the technical and cultural rise of agent-first systems, the potential decline or radical transformation of UX, and the wider consequences for design as a discipline. While some argue that UX will not disappear but simply evolve, others foresee its decline as a distinct profession. The truth likely lies in a complex middle ground where UX designers must redefine their value in an environment where agents, not humans, are the primary users of software.

The Historical Centrality of UX

From Command Lines to GUIs

In the early era of computing, user interaction with systems was conducted through command-line interfaces. This required a level of technical literacy that excluded most people. The advent of graphical user interfaces in the 1980s marked a democratization of computing, allowing ordinary users to interact with software through visual metaphors such as windows, icons, menus, and pointers.

This revolution made design essential. Companies like Apple distinguished themselves through user-friendly interfaces that emphasized simplicity and accessibility. UX as a concept emerged from this wave, emphasizing that the ease and delight of use were as important as raw functionality.

The Web and Mobile Era

The internet expanded the importance of UX further. The web browser became the most universal interface, and with it came a need to design intuitive navigation, clear information hierarchies, and responsive layouts. As commerce, entertainment, and communication shifted online, UX became critical to competitive differentiation.

Mobile computing intensified this need. With smaller screens and touch-based input, designers had to rethink paradigms once again. The mantra of “mobile-first” design reshaped entire industries. Success in app ecosystems often hinged on subtle aspects of design: how onboarding worked, how easily a feature could be found, and how naturally gestures aligned with user expectations.

UX as Strategy

By the late 2010s and early 2020s, UX was no longer a support function but a strategic discipline. Companies recognized that design shaped brand identity, customer loyalty, and market dominance. Firms like Airbnb, Uber, and Spotify owed much of their growth to intuitive user experiences. Tech giants built massive UX research teams. Universities expanded programs in human-computer interaction.

This golden age of UX coincided with the rise of AI but framed AI as a tool to enhance user-facing experiences: personalization, recommendations, and conversational interfaces. What few anticipated was that AI would stop being an invisible layer and instead become the user itself.

The Rise of AI-Agent First Systems

From Assistants to Autonomous Agents

AI assistants such as Siri, Alexa, and Google Assistant introduced mainstream audiences to the idea of conversational interfaces. Initially, these tools were supplementary, helping users set reminders, play music, or retrieve information. They coexisted with traditional interfaces rather than replacing them.

The next stage was far more ambitious. Large language models (LLMs) and multimodal AI systems demonstrated an ability to parse natural language instructions, navigate APIs, and autonomously complete complex tasks. Instead of pointing and clicking through menus, users could simply tell an AI what they wanted, and the AI would execute it.

This shift signals a deeper transformation. Rather than designing interfaces for human navigation, companies are beginning to design systems where AI agents handle navigation, execution, and even optimization.

Agents as the New Users

In an AI-agent first world, the software “user” is not the human but the agent acting on their behalf. For example, instead of an employee logging into multiple dashboards to generate a report, they may instruct an agent to retrieve, analyze, and visualize the data. Instead of a consumer browsing through an e-commerce site, they may tell an AI concierge to select a product, negotiate pricing, and complete the purchase.

In such scenarios, the agent interacts with other software through APIs, structured data exchanges, and machine-readable protocols. The graphical interface becomes secondary or unnecessary. This directly challenges the traditional role of UX design.

Economic and Technical Drivers

Several forces accelerate this transition:

1. Efficiency: Agents can operate at machine speed, completing in seconds what would take humans hours.

2. Complexity: Modern systems are too intricate for users to navigate effectively. Agents simplify complexity by abstracting interfaces.

3. Personalization: Agents can tailor actions precisely to a user’s preferences, far beyond what a static interface can achieve.

4. Ubiquity of APIs: More systems expose programmable interfaces, making agent-to-system interaction easier than ever.

5. Cost Reduction: Enterprises save money by automating repetitive workflows that previously required human navigation of software.

Together, these drivers suggest that the agent-first model will not be a fringe experiment but a mainstream paradigm.

The Decline of Traditional UX Roles

Interfaces for Machines, Not People

As agents become the dominant navigators, software may prioritize machine interfaces over graphical ones. Instead of polished dashboards, applications may focus on robust APIs, structured schemas, and agent-friendly ontologies. The design considerations shift from human readability to machine interoperability.

This does not eliminate the need for UX entirely, but it changes its focus. The “experience” becomes invisible to the end user, who only interacts with the agent. The software behind the agent may never be seen. This reduces demand for traditional interface designers.

Redundancy of Usability Testing

Usability testing has long been a cornerstone of UX. Designers observe users attempting tasks, identify pain points, and refine interfaces. But if agents, rather than humans, are the primary users, the logic of usability testing collapses. Agents do not get frustrated by unclear menus or misaligned buttons. They parse code and protocols directly. Testing shifts toward performance, latency, and error handling, which are engineering rather than design concerns.

The Risk of Commodification

If UX becomes less central, the profession risks commodification. Already, automated tools generate interface components, design systems standardize aesthetics, and templates reduce differentiation. In an agent-first world, many interfaces may only exist for legacy reasons or regulatory compliance. The specialized creativity of UX designers may be marginalized.

Counterarguments: UX Will Evolve, Not Disappear

The Human-Agent Interface

Even in an agent-first paradigm, humans still need to communicate with agents. This interaction becomes a new frontier for UX. The design of prompts, natural language interfaces, and multimodal interactions will require expertise. Prompt engineering, conversational design, and emotional alignment become central concerns.

Trust, Transparency, and Explainability

One of the greatest challenges of agent-first systems is trust. Users must understand what agents are doing on their behalf. UX professionals can design transparency mechanisms, explainability dashboards, and consent frameworks. The goal is not to design interfaces for task execution but for oversight, trust-building, and accountability.

Hybrid Systems

Not all tasks are suited to full automation. Many require human judgment, creativity, or ethical reasoning. Hybrid systems, where agents collaborate with humans, still need thoughtful design. The handoff between human and agent is itself a UX challenge. Designers must craft workflows that allow seamless collaboration without confusion or loss of control.

Broader Consequences for Design

Redefinition of Skills

The decline of traditional UX does not mean the decline of design altogether. Instead, it signals a need for designers to acquire new skills. These include systems thinking, human-AI interaction, prompt design, and even policy literacy. Designers will play roles in shaping not just interfaces but socio-technical ecosystems.

The Ethical Dimension

In an agent-first world, ethical design becomes more urgent. If users rarely see the underlying systems, they may be vulnerable to manipulation, hidden biases, or opaque decision-making. UX professionals could evolve into ethical guardians, ensuring that agent-mediated experiences respect human autonomy and dignity.

From UX to HX (Human Experience)

Some argue that the field may shift from “user experience” to “human experience.” Instead of optimizing for clicks or navigational ease, designers optimize for meaning, trust, and holistic well-being in agent-mediated interactions. The scope broadens from micro-interactions to macro-social impacts.

The Future of UX Education and Employment

Shifts in Academic Programs

Universities teaching human-computer interaction may pivot toward human-AI interaction. Courses in interface design may shrink, replaced by studies in conversational systems, explainable AI, and algorithmic accountability.

Industry Trends

Employment in traditional UX may contract, especially in industries heavily adopting agents. However, new niches will appear in designing agent oversight tools, regulatory compliance interfaces, and AI ethics frameworks. Designers who adapt quickly may thrive, but others may face obsolescence.

The Risk of Polarization

The profession may split into two tracks:

1. Legacy UX: Serving industries and populations that still rely on traditional interfaces.

2. Next-Gen UX: Designing interactions between humans and agents, with emphasis on trust and oversight.

This polarization mirrors past transitions, such as the decline of print design in favor of digital media.

The rise of AI agents as primary navigators of systems represents a seismic shift in the technology landscape. It challenges the foundations of the UX profession, which has thrived on designing interfaces for human navigation. As agents take over those roles, traditional UX may decline in importance, becoming marginalized or commodified.

Yet decline is not the same as extinction. UX can evolve into new domains, focusing on human-agent communication, trust-building, and hybrid collaboration. The future of the profession lies not in resisting the agent-first world but in redefining itself within it.

UX professionals who embrace this shift can shape the next chapter of human-technology interaction. Those who cling to the old paradigm may find their skills increasingly irrelevant. The choice for the profession is clear: adapt and expand, or fade into history.

Just Three Things

According to Scoble and Cronin, the top three relevant and recent happenings

​​OpenAI to Launch First Custom AI Chip with Broadcom in 2026

​​OpenAI plans to produce its first custom artificial intelligence chip in 2026 through a partnership with U.S. semiconductor giant Broadcom, according to sources cited by the Financial Times. The chip will be used internally within OpenAI’s infrastructure rather than sold externally, part of a broader strategy to reduce its growing reliance on Nvidia and diversify its supply chain. OpenAI has already been working with Broadcom and Taiwan Semiconductor Manufacturing Co. (TSMC), and earlier this year finalized the chip design, preparing it for fabrication. Broadcom's CEO, Hock Tan, confirmed that the company has secured over $10 billion in AI infrastructure orders from a new, unnamed customer (widely believed to be OpenAI) contributing to optimistic projections for its AI-related revenue growth in fiscal 2026.

Anthropic to Pay $1.5 Billion to Settle Authors’ Copyright Lawsuit

Anthropic, the AI company behind the Claude chatbot, has agreed to pay $1.5 billion to settle a class-action lawsuit brought by authors who accused it of using pirated books to train its models. The settlement, pending a judge’s approval, is the largest copyright recovery ever reported in the U.S. In the agreement, Anthropic will compensate rights holders with approximately $3,000 per book across roughly 500,000 works, destroy the infringing datasets, and not admit any wrongdoing. The case stems from a June 2025 ruling that, while using legally purchased books for AI training could be considered fair use, the acquisition and storage of pirated digital copies of copyrighted books were not. This landmark resolution marks a significant legal milestone in the ongoing debate over how AI companies source and use copyrighted materials. CNBC

AI Bible Videos Turn Scripture into Blockbuster-Style Entertainment

​​The AI Bible project, run by Pray.com, is producing AI-generated videos that reimagine biblical stories with dramatic, Hollywood-style visuals. One popular video depicting the Book of Revelation has drawn hundreds of thousands of views, mostly from younger audiences, and Pray.com leaders say viewers find the content spiritually meaningful. Supporters describe it as a creative way to bring scripture to life, likening it to a “Marvel Universe of faith,” while critics argue it trivializes sacred texts, turning them into entertainment rather than divine revelation. Theologians warn that such flashy, action-oriented portrayals may distort the Bible’s message, while others believe the videos could spark renewed interest in scripture, even if the interpretations are controversial.
