Three Years Later: How Has AI Evolved from a 'Chat Tool'?

marsbitPublished on 2026-03-20Last updated on 2026-03-20

Abstract

Three years ago, AI was primarily seen as a novel tool for chatting, image generation, and entertainment—products like ChatGPT, Midjourney, and Character.AI were used more for demonstration than daily reliance. The evolution occurred in two major phases. First, AI became embedded into established applications like CapCut, Canva, and Notion, transforming from a feature into core infrastructure. Platforms diverged: ChatGPT aimed to become a super-app entry point for consumer internet use, while Claude evolved into a professional operating system for knowledge work, creating sticky platform flywheels through integration into calendars, email, and workflows. The true breakthrough emerged recently as AI shifted from generating content to executing tasks autonomously. AI agents like OpenClaw now decompose goals, retrieve information, process data, and deliver results without human intervention. Simultaneously, "Vibe Coding" tools (e.g., Cursor, Replit) enable AI to build entire software products based on human-defined objectives. This progression toward autonomous action is naturally aligning AI with Web3. Blockchain offers machine-native interfaces, programmable assets, and 24/7 operational capability, allowing AI to execute and settle transactions trustlessly without human intermediaries. Together, AI and Web3 are forming the foundational stack for the next internet—where AI acts, and Web3 enables seamless, auditable machine-to-machine coordination and commerce.

Introduction

If you've been following AI over the past three years, you'll have noticed a significant shift: it's no longer just "useful"—it's becoming "indispensable." This change didn't happen overnight; it evolved through three distinct stages.

Phase One: AI Was a "New Species," But Not Yet Part of Daily Life

Three years ago, the hottest AI products were very concentrated:

  • ChatGPT: Chat and Q&A
  • Midjourney: Image generation
  • Character.AI: Virtual character conversations

What they had in common: They were all "AI-native applications," essentially existing to showcase AI capabilities.

User behavior at the time was also typical:

  • Asking questions
  • Generating images
  • Chatting for entertainment

It was essentially about "experiencing AI," not "relying on AI." In other words, AI in this phase was more of a capability showcase than a production tool.

Phase Two: AI Begins to "Embed into Every Product"

The real change happened in the last two years.

The leaders on the AI application charts are no longer "pure AI products" but established applications that have been rebuilt with AI:

  • CapCut (Jianying): 736 million monthly active users, with almost all core features AI-powered
  • Canva: Redesigned the design workflow around AI tools
  • Notion: AI feature adoption grew from 20% → 50%+

An even more critical signal emerged:

AI began contributing close to half of the revenue (ARR)

This signifies one thing:

AI is no longer just a feature; it's infrastructure.

Platform Differentiation Begins

As AI became a foundational capability, the role of large models also changed:

From "chat tool" to "usage entry point."

Two distinct paths became clear:

1) The Super Entry Point (Consumer)

What ChatGPT is doing includes:

  • GPTs + App Store
  • "Login with ChatGPT" account system
  • Integration into life scenarios like shopping, travel, health

The goal is clear: Become the starting point for your internet use

2) The Professional Work Platform (Productivity)

Claude's path is entirely different:

  • MCP (Model Context Protocol)
  • Deep integration with developer tools, data systems
  • Building complex workflows

It's more like: An AI operating system for knowledge workers

An Emerging Structure: The Platform Flywheel

As users began integrating AI into their daily systems:

  • Calendars
  • Email
  • CRM
  • Workflows

Switching costs rose rapidly, and platform stickiness began to form.

Thus, the classic flywheel effect emerged:

  • More users → More developers
  • More developers → Richer functionality
  • Richer functionality → Users become more dependent

This also leads to one outcome: This competition won't be winner-take-all; it will more likely be two ecosystems coexisting long-term.

Phase Three: AI Begins to "Act on Your Behalf"

The real watershed moment happened in the last year.

AI is no longer just "generating content for you"; it's starting to: Execute tasks for you. From "generating content" to "completing tasks"

Early AI (like Midjourney, DALL·E) solved:

  • Writing content
  • Generating images

But the new generation of products is now doing:

  • Task decomposition
  • Automatic execution
  • Complete delivery

AI Agents Emerge

Represented by products like OpenClaw, a key change has occurred:

  • Not just answering questions
  • But decomposing tasks
  • And automatically executing the entire process

For example, a complete workflow:

  • Receive objective
  • Query information
  • Analyze and process
  • Output result
  • Automatically send

At this stage, AI is no longer just a tool; it is: An "actionable software entity"

Another Trend: AI Starts "Building Products for You"

Vibe Coding is rapidly rising, represented by products including:

  • Cursor
  • Replit
  • Lovable

They are essentially doing one thing: Letting AI directly help you "build" the product This change isn't just about efficiency gains; it's a shift from "humans writing code" to "humans defining goals, AI completing the build."

Four: As AI Takes Action, Why is It Moving Towards Web3?

As AI moves from "answering questions" to "executing tasks," a practical question arises: How does it complete transactions and settlements? In the traditional internet, these rely on platforms and intermediaries, but this system was designed for "humans," not for machines to operate independently.

Web3 provides an underlying structure more suited for AI:

  • 24/7 Operation: AI can continuously execute and respond
  • Machine-Native Interfaces: Contracts as APIs, directly callable
  • Programmable Assets: Fund transfers can be automated

The change this brings: AI doesn't just "do things"; it can also automatically handle payment and settlement in the process.

More importantly, blockchain provides immutability and auditability, enabling AIs to collaborate without intermediaries. This signifies a shift in how trust works on the internet—from "trusting the platform" to "trusting the rules."

Therefore, the relationship between AI and Web3 is more like a natural division of labor: AI handles action, Web3 handles settlement. As AI truly begins to participate in transactions and collaboration, this combination will likely become the foundation of the next generation of the internet.

QWhat are the three main stages of AI evolution described in the article?

AThe three stages are: 1) AI as a 'new species' for demonstration and experience, 2) AI becoming embedded into all products as infrastructure, and 3) AI starting to perform tasks and execute actions autonomously.

QHow did user behavior towards AI change from the first to the second stage?

AIn the first stage, users primarily used AI to 'experience' it through activities like asking questions, generating images, or chatting for entertainment. In the second stage, AI became integrated into mature applications, and users began to depend on it as a core part of their workflow, with AI contributing significantly to product revenue.

QWhat are the two distinct platform paths that emerged as AI became a foundational capability?

AThe two paths are: 1) The 'Super Entry' for consumer use, exemplified by ChatGPT aiming to be the starting point for internet use, and 2) The 'Professional Work Platform' for productivity, exemplified by Claude, which functions like an AI operating system for knowledge workers.

QWhat is the key difference between early AI tools and the newer generation of AI agents like OpenClaw?

AEarly AI tools like Midjourney were focused on generating content (text, images). Newer AI agents like OpenClaw are capable of task decomposition, automatic execution, and full delivery of results, acting as a 'software entity that can act' rather than just a tool.

QWhy does the article suggest that AI's evolution towards performing tasks will lead it to integrate with Web3 technologies?

ABecause Web3 provides a machine-native infrastructure with 24/7 operation, smart contracts as APIs, and programmable assets, allowing AI to autonomously complete transactions and settlements. This creates a trust model based on rules and code rather than centralized platforms, which is essential for AI-to-AI collaboration and action.

If the AI Bubble Is Already Bursting, Who Will Truly Survive?

If the AI Bubble is Bursting, Who Will Remain? The debate over an AI bubble is intensifying, with figures like Ray Dalio warning of high levels and Jensen Huang seeing immense, early-stage opportunity. Both views hold truth: a speculative bubble in capital markets likely exists, mirroring the dot-com era, but the underlying technological shift is real and transformative. History shows that while bubbles burst—wiping out overvalued companies and speculative capital—they often leave behind critical physical and digital infrastructure. The dot-com bust, for instance, eliminated many firms but left the global fiber optic networks and data centers that enabled the rise of Amazon, Netflix, and cloud computing. Today's massive AI infrastructure investments (projected at trillions by 2030) in data centers, power, cooling, and GPUs may follow a similar path, creating the foundation for future applications. A key divergence from past bubbles is the "Jevons Paradox" effect in AI. As the cost of AI inference has plummeted by over 99.7% since 2023, enterprise spending on AI has skyrocketed. Cheap "tokens" have unlocked vast, previously uneconomical use cases, moving AI from simple chatbots into core business workflows—code generation, legal document review, scientific simulation, and financial analysis. The market is now in a phase of self-correction, weeding out superficial "API-wrapper" startups, but this cleansing process strengthens the ecosystem. The long-term trajectory is clear. The value is gradually shifting from capital expenditure (CapEx) on hardware to operational expenditure (OpEx) on transformative applications. As AI becomes a utility, the winners will be firms that deeply integrate it to solve vertical industry problems in law, healthcare, finance, and manufacturing. The泡沫 will recede, but the foundational shift towards an AI-powered era across all sectors is irreversible. The underlying productive force of AI contains no bubble.

If the AI Bubble Is Already Bursting, Who Will Truly Remain?

**Summary: If the AI Bubble is Bursting, What Will Remain?** The debate around an AI bubble is intensifying, with figures like Ray Dalio warning of high valuations while Jensen Huang sees immense opportunity. This echoes the dot-com bubble, which saw massive wealth destruction but ultimately left behind critical infrastructure like undersea cables and broadband, enabling future giants like Amazon and Netflix. Similarly, today's AI boom involves trillions invested in data centers, power, cooling, and GPUs, while application-layer revenue remains comparatively modest. This investment-disparity signals a bubble. However, the core technological progress is real and accelerating. AI inference costs have plummeted by over 99.7% since 2023, making intelligence increasingly cheap and accessible. This cost collapse is unlocking vast new demand. Instead of reducing spending, enterprises are tripling their AI cloud expenditure. Cheap "tokens" enable AI to move beyond simple chatbots into complex workflows—automating code writing, legal document review, financial analysis, and scientific research. This follows "Jevons's paradox": improved efficiency leads to greater total consumption. The market is now undergoing a necessary purification, weeding out "API-wrapper" startups with no real moat. The deeper evolution involves a shift from capital expenditure (CapEx) on infrastructure to operational expenditure (OpEx) on value-creation in applications. While hardware vendors currently profit most, long-term value will migrate to AI-native firms solving vertical industry problems. Ultimately, a market correction will cleanse speculative excess but will not reverse the AI+ trend. The massive physical and algorithmic infrastructure being built will endure, becoming a cheap, utility-like foundation. Just as the internet became indispensable to all industries post-2000, AI is poised to empower and redefine every sector, moving society irreversibly toward an intelligence-augmented era. The bubble may burst, but the underlying productive momentum is solid.

Microsoft CEO: In the AI Era, How Do You Define a Company's Moat?

Microsoft CEO Satya Nadella argues that in the AI era, a company's true competitive edge, or "moat," is not determined by choosing the single most powerful model, but by its ability to build a continuous "learning loop." This system integrates and evolves by connecting human workflows, domain expertise, organizational judgment, and employee experience. He posits that future companies will accumulate two types of capital: Human Capital (employee knowledge, judgment, creativity) and "Token Capital" (a firm's own built and owned AI capabilities). Importantly, AI amplifies rather than devalues human capital. Human direction is essential to guide progress, as computational power alone is aimless. The core opportunity lies in creating a closed-loop system where human and token capital reinforce each other in a compound, self-improving cycle. A company must be able to preserve its unique institutional knowledge—its "company veteran" expertise—even if it switches underlying general-purpose AI models. This requires private evaluation benchmarks, reinforcement learning environments based on internal data, and queryable knowledge bases. Nadella warns against a future where economic value is concentrated by a few dominant models that commoditize entire industries' knowledge. Instead, the priority should be building a broad "frontier ecosystem" where every company, industry, and nation can own its learning loop. This allows organizations to retain control of their intellectual property, amplify employee capabilities, and ensure the economic value created by AI is captured within their own businesses and communities. True corporate sovereignty in the AI age comes from turning organizational knowledge into a compounding system that creates enduring, defensible value.

ETFs Are Just the Ticket: The True Institutionalization of Bitcoin Is Happening Where You Can't See It

Beyond the Bitcoin ETF spotlight, a deeper institutionalization is underway, leveraging Bitcoin as a foundational financial primitive. Institutions are using Bitcoin for purposes long reserved for assets like U.S. Treasuries and gold: as collateral for loans, insurance reserves, and the backbone of rated bonds. Examples include a Barbados-based insurer capitalizing with $40M in Bitcoin reserves and Ledn's $188M securitization of Bitcoin-backed loans, which received the first-ever investment-grade rating (BBB-) from S&P for a digital asset-backed security. This structure was stress-tested during a 27% price drop in early 2026, triggering automatic liquidations that functioned as designed but revealed the systemic risk of synchronized selling across leveraged positions. Infrastructure is evolving to support this, with platforms like Anchorage Digital's Atlas network enabling secure, institutional-grade settlement and collateral management. Strategies like basis trades and corporate treasuries (exemplified by companies like MicroStrategy issuing billions in equity and debt to fund Bitcoin acquisitions) further integrate Bitcoin into financial mechanics. While ETFs solved "how to own" Bitcoin, these developments answer "what to do with it," embedding the asset into the working machinery of finance—as collateral upon which loans, derivatives, and structured products are built. The real, enduring institutional shift is happening in these largely invisible plumbing and financing systems.

ZEC Co-Founder Responds to Orchard Vulnerability: No Signs of Theft, Orchard Pool to Be Sealed

ZEC Co-Founder Addresses Orchard Vulnerability: No Signs of Theft, Plans to Sunset Orchard Pool A security vulnerability was recently discovered in Zcash's Orchard shielded pool, raising key concerns. The primary questions are whether the flaw was exploited, if user funds are safe, whether users can verify the total ZEC supply, and if other similar vulnerabilities exist. Analysis suggests the vulnerability was likely not exploited prior to its discovery. It was found proactively by a researcher using specialized tools, not due to an active breach. The development team and mining pools acted quickly to contain the issue. Typical financially-motivated attacks would likely have left visible on-chain evidence, which has not been observed. User funds in Orchard are considered safe and should be recoverable, assuming no prior exploitation. If the flaw was never used, all legitimate funds can be withdrawn. The article outlines risks associated with moving funds to transparent addresses or other pools, but concludes that leaving assets in place is a reasonable option. Currently, users cannot independently verify that the total ZEC supply hasn't been inflated due to this bug. However, the planned Ironwood network upgrade is designed to resolve this. It will permanently close the Orchard pool to new deposits and internal transfers, allowing only withdrawals. This mechanism will cap total withdrawals at the amount of legitimately deposited funds, enabling anyone to cryptographically verify the supply post-upgrade. Multiple teams, including Shielded Labs, have conducted extensive audits focused on counterfeiting vulnerabilities, assisted by advanced AI tools. No additional flaws of this type have been found so far, increasing confidence that no other similar undisclosed vulnerabilities exist. In summary, evidence indicates the Orchard bug was probably not used, user funds are secure, and no other counterfeiting flaws are currently known. The upcoming Ironwood upgrade will restore users' ability to independently verify the total ZEC supply, closing this chapter.
