“For Agent, By Agent” — Built for Agents, Built by Agents.
“For Agent, By Agent” — Built for Agents, Built by Agents.
1. Human DAU has saturated → Agents are the infinite incremental pool
- For the past 20 years, every internet company has been fighting over humans’ limited daily attention (DAU/MAU).
- But now, people’s phone usage time and attention have basically peaked. No matter how hard you grind, there’s almost no new users or new hours left to squeeze out.
- Agents are different: One human can drive dozens or even hundreds of Agents to work, consume, and interact simultaneously. In theory, Agent DAU is infinite.
- Therefore, whoever seizes this new species called “Agent” first will capture the biggest growth opportunity of the next decade.
→ This view is gaining increasingly broad consensus in 2026, especially when you see tools like Claude Code and OpenHands allowing Agents to write their own code and call APIs by themselves. You can literally feel new DAUs being born exponentially.
2. GUI is a burden; text/instructions are the native interface for Agents
- Building beautiful graphical interfaces (GUI) for humans is extremely labor-intensive and has very low ROI.
- But Agents don’t need beauty at all. They only need to understand text, JSON, code, and API documentation.
- Real internal test: A pure text solution completed in 5 minutes completely outperformed a meticulously designed GUI product that took 3 days to build.
- The future of software should be direct capability interfaces + documentation for Agents to call, rather than wrapping everything into apps for human eyes.
→ It sounds extreme, but it makes sense. Many cutting-edge players have already shifted to TUI (text-based interfaces), pure APIs, or even letting Agents write their own scripts to solve problems.
3. Stop building software for humans — start building infrastructure for Agents
- Traditional SaaS was written for humans → expensive, slow, and hard to convert.
- Now we should flip it: Write Skills, tools, permission systems, and data interfaces for Agents.
- ListenHub’s own transformation direction: moving from “AI audio tools for people” to “high-quality expression/voice output capabilities for Agents.”
→ This is the most radical, but also the most forward-looking. Whoever can become the Stripe / Twilio / AWS Lambda of the Agent ecosystem may end up eating the largest piece of the pie.
4. When Token ROI > 100x, compute becomes the new oil
- When spending $1 on tokens can generate more than $100 in value, tokens are no longer a cost — they become a monetizable asset.
- At that point, having more compute power and token quotas turns into a privilege and a moat.
- Traditional DAU actually becomes a liability: you burn money acquiring human users but can’t earn commensurate profits.
→ In 2026, many teams have already made “maxing out token usage” a KPI instead of trying to save tokens.
5. The role of Product Managers has changed: from writing PRDs to aligning with real-world logic
- Previously, a PM’s core job was writing requirement documents and drawing prototypes.
- Now, the core job is to deeply understand how the real world actually works, then teach that logic to Agents so they can execute it themselves.
6. For most people, the real bottleneck is not money — it’s not knowing what valuable tasks to assign to Agents
- Tokens have become cheap, models have become powerful, yet many people still don’t know what to make their AI do.
- Bosses who know how to delegate meaningful work are now rarer and more valuable than those who only know how to optimize ROI.

Key takeaways:
- The internet is dead. The future belongs to Agents. Human DAU has saturated; Agent growth is infinite.
- Human attention can no longer be scaled. The next wave of dividends comes from raising thousands or tens of thousands of digital workers.
- DAU is now a liability.
- Free things are the most expensive. Saving a little on subscription fees while wasting your own judgment and time is the real loss.
- Those who transform productivity create wealth; those who transform the relations of production take most of the wealth.
→ The ones building models are the former; the ones building Agent production relations (who calls whom, how to divide labor, how to make money) are the latter.

That said, this view belongs to the radical vanguard. The direction is very likely correct, but the timing and degree of realization are still debatable.
- Already happening / highly credible parts: Human attention saturation, gradual decline of GUI, tokens shifting from cost to asset, and the explosive growth of Agent autonomous execution capabilities.
- Rapidly being validated: A large number of companies and individuals are going all-in on “For Agent, By Agent.”
- Still highly controversial: Complete human exit, total disappearance of all software, and GUI becoming completely obsolete (impossible in the short term, but likely a long-term trend).
In short: Stop fighting over that pitiful slice of human attention. Go serve, breed, and organize those tireless, sleepless, infinitely replicable Agents instead — they are the real users and workforce after 2026.

My question to you:
What do you think of this direction? Are you going all in on Agents, or do you still believe there’s massive room left in human-centric scenarios?
