Many people are now discussing artificial intelligence and cryptocurrency, and they automatically assume that the two will deeply integrate.

But I am actually increasingly skeptical that most so-called AI x Crypto projects are just sharing the same market sentiment rather than having genuine structural intersections.
What truly belongs to AI is intelligent production; what truly belongs to Crypto is permissionless value coordination.
Only when AI begins to have economic behavior will the two truly overlap.
That’s also why I’ve always believed that most AI products don’t really need blockchain.
An AI search engine doesn’t need a token; an AI video generator doesn’t need a chain; many projects are just packaging fundraising narratives as technological integration.
But there are three scenarios where I believe blockchain is almost irreplaceable.
The first is machine payments: in the future, AI agents will definitely autonomously call APIs, purchase data, pay for computing power, and even hire other agents to collaborate.
Traditional banking systems cannot support this kind of global, millisecond-level, API-driven machine trading.
So stablecoins will naturally become the default payment layer for AI.
The second is machine reputation: in the future, the biggest trust issue on the internet may no longer be whether a person is trustworthy, but whether an agent is stable.
AI systems need long-term collaboration, and such collaboration requires reputation records.
Therefore, the true long-term value of DID and on-chain reputation may not be serving human identities, but serving AI identities.
The third is machine coordination: many underestimate the true significance of smart contracts.
Its greatest value may not be replacing laws, but enabling machines to automatically fulfill agreements.
But I am not optimistic about fully decentralized training; training the most advanced models requires ultra-high-density compute scheduling and low-latency communication, and centralized clusters still remain the most efficient.
So many decentralized training projects are more like marketing concepts; the real opportunities are in decentralized inference and edge computing markets because they are better suited for fragmented resources.
Another overhyped narrative is that all agents will go on-chain; I believe they won’t. In the future, most agents will only call on-chain systems when payment, reputation verification, or protocol execution is needed.
Blockchains are more like the economic layer for AI, not the operating system for AI.
Currently, I believe the most underestimated direction is AI-native companies; in the future, organizations may emerge without employees, offices, and be entirely operated by agents.
And their financial systems are likely inherently on-chain.
I even suspect that the largest on-chain user base in the future might not be retail investors, but AI.
So, the true intersection of AI and crypto is actually narrower than the market imagines.
