Mark Zuckerberg spent $80 billion trying to convince the world to live inside a cartoon.
He failed. Last week, Meta quietly shuttered Horizon Worlds, the avatar-and-Eiffel-Tower virtual social platform that became the punchline of a generation. The obituaries were swift and merciless. One viral post catalogued a man who had spent his digital fortune buying beachfront property in a world that is now a mobile app. "The frontier closed last week," the post read.
But here is the question nobody is asking: what if this funeral is actually a groundbreaking ceremony?
William and I-man tackled the Horizon shutdown on Episode 307 of The Block Runner Podcast, and their read is sharply different from the headlines. The shutdown of a closed, corporate metaverse does not kill the metaverse thesis. It removes the biggest, most well-funded adversary the open metaverse ever had.
The Block Runner crew has been in this space since 2019. They were building in Decentraland during the alpha, experimenting with applications when MANA was trading at two cents per token. They have watched Zuckerberg change his company's name and watch MANA rip 250x in response. They have seen the full cycle.
"Whenever you do anything crypto, you always got to have a big bad wolf in the room," William explained on the episode. "Meta, NVIDIA. These companies are closed metaverse, meaning they're just going to try and bring you in and siphon as much data from you as they can. Crypto is supposed to be like the antidote to that."
The distinction is not semantic. A closed metaverse is a feudal system: Meta owns the land, the rules, and the exit. An open metaverse is a protocol: the land is tokenized, the rules are on-chain, and no single company can pull the plug. What died last week was the feudal system. The protocol is still running.
The real problem, as William and I-man framed it, is not the death of the metaverse but the absence of a killer app. "It's missing in the same way that AI has been in development for 30 years," William said. "And then all of a sudden someone came up with generative transformers, and you could talk to AI and it could actually produce something of value." The metaverse needs its ChatGPT moment. It has not arrived yet.
But AI might be the thing that delivers it.
Building a video game is expensive. Building a movie is expensive. The metaverse, which runs on video game technology, has always been trapped behind the same cost wall. That wall is dissolving.
William made the argument on the episode that AI drastically reduces the cost of creating virtual experiences. The same vibe coding revolution that lets a solo developer ship a working SaaS product in a weekend could let a small team build a Roblox-quality experience inside Decentraland. "Imagine instead of UGC coming from humans," he said, "it comes from agents and from vibe coders who are using agents to build out experiences."
Roblox has 100 million monthly active users not because it has better graphics than Horizon Worlds but because it has an endless supply of user-generated content. New experiences appear constantly. The community is the engine. The open metaverse has never had that flywheel because building is too hard and the economic incentives for creators are unclear.
AI removes the building barrier. What the open metaverse still needs is the economic layer, and that is a conversation for a different episode.
Barry Silbert, the investor largely responsible for the early institutional push into Web3 metaverse assets, recently posted a public tweet asking Decentraland where he could read about their AI integration efforts. William and I-man noted the significance: Silbert has direct communication channels with the Decentraland team. He does not need to ask publicly. The fact that he did suggests he is frustrated by the pace.
"If I were Decentraland, I would be all in on AI agent implementation into the metaverse," William said. "Take a break from the dancing."
Buried beneath the metaverse news was a piece of regulatory history that the market barely flinched at, which is itself a data point.
The SEC issued a formal interpretation clarifying federal securities laws as applied to crypto assets. The headline finding: meme coins, NFTs, digital collectibles, and most utility tokens are not securities. Stablecoins under the GENIUS Act are not securities. Tokenized equities still are.
"It's more of a foundation," I-man said. "People have been operating under these conditions anyways, without the clarity. But with these new actual vectors of clarity, you know, will new participants enter the market? Probably."
The fact that Bitcoin barely moved on the news is not proof the news does not matter. It is proof the market is deep in bear territory. "This is pretty much deep in bear market territory," William observed. "You would expect news like this to really accelerate things, but that is not the part of the market cycle we are in."
Bear markets are when foundations get poured. The SEC clarity, the stablecoin legislation, the incoming frameworks for American participation in tokenized securities offerings: these are the cement footings. When the cycle turns, builders will have a legal surface to stand on that did not exist before.
If there is one through-line in The Block Runner's worldview, it is this: the Bitcoin security budget problem is real, it is mathematical, and it is going to matter long before most people expect.
William laid out the mechanics plainly on Episode 307. Bitcoin miners fund network security through the block subsidy, the freshly minted BTC they earn per block. That subsidy halves every four years, by design. Halving sounds like a feature until you run the math out over 50 years. An exponentially decaying subsidy against a security requirement that should only grow as Bitcoin's market cap grows creates a gap. That gap is eventually funded by transaction fees alone. Whether fees will be sufficient is an open, heavily contested question.
NAT token, in William's framing, is a second subsidy. It does not halve. Miners earn NAT alongside BTC for including NAT transactions in blocks. "NAT is literally the only token that exists within cryptocurrency that really helps Bitcoin," William said. "Every other token that exists goes to compete with Bitcoin. Every single one."
The four mining pools currently supporting NAT are all based in the East, a cultural distribution William finds significant. Asian communities, he argued, are more willing to engage with fundamental analysis and long-term protocol reasoning than Western crypto traders who are focused on momentum and narrative cycles. "The evidence suggests you're right," I-man noted. "If you look at the four miners that are supporting the NAT token, all of them are in the East."
Since Magic Eden's departure from the Bitcoin Ordinals space, NAT has roughly doubled in price. The Binance Smart Chain integration is live. Spiderpool's dashboard is incoming. NAT.fun, The Block Runner's own product that integrates NAT tokens directly into its economy, is approaching launch.
Whether NAT achieves its thesis depends on miner adoption at scale. That is still years away. But the community is three years old, the 24-hour spaces on X have hundreds of participants, and the thesis has not changed. That kind of sustained conviction in a bear market is rare.
The episode's most grounded segment was not about Bitcoin or the metaverse. It was about a chemical engineer in Houston who built something his entire industry needs.
His tool reads piping isometric drawings and automatically extracts weld counts, material specs, and commodity codes. A process that took 10 minutes per drawing now takes 60 seconds. A batch of 100 drawings that would have taken a team days now runs in five minutes. He packaged it, built a landing page, and started selling it to other contractors.
"He's not the guy," William said. "He's just a guy who understands that he's got some new superpower ability, and he could use that to his advantage."
The professional engineering industry is one of the highest-stakes domains in existence. Incorrect schematics in a chemical plant do not result in a bad app review. They result in explosions, collapses, and courtrooms. The culture is conservative by necessity, and software built in the 1990s is still running critical infrastructure. That conservatism creates an enormous gap between what is possible with AI today and what has been deployed in the field.
That gap is an opportunity. The person who fills it does not need to be a startup founder or a Silicon Valley transplant. They just need domain knowledge and enough curiosity to pick up a new tool. "You have a domain, you apply that with your AI interest, and really come up with something useful for your industry," William said. "That is the real opportunity."
This same principle applies to what The Block Runner is building with its own podcast pipeline. What used to require a human editor and multiple hours of production time now runs in ten minutes after the recording ends. The MP4 drops into a folder. An agent handles the rest: transcription, metadata generation, audio normalization, episode assembly, and distribution. The team can now focus entirely on the conversation, not the production.
Goldman Sachs recently reported that massive AI investment contributed essentially nothing to U.S. economic growth last year. The "AI is a bubble" crowd got louder. William and I-man pushed back.
"Right now we're in a very much up period, but who knows, maybe these FUD vectors are giving us forewarning," William said. "It's going to take a little bit longer than what most people anticipated for an actual economic upswing to come from all this."
The comparison to crypto's own history is instructive. Banks collapsed in 2023. USDC briefly de-pegged. People wrote the obituaries for DeFi, NFTs, and Web3. Hyperliquid got built. Polymarket found product-market fit. The S&P 500 got perpetual contracts on-chain. The next cycle will look back at this period as its foundation.
The same pattern is playing out in AI. The economic returns look slow because companies are in the cost-reduction phase. Workforce optimization is step one. Revenue expansion comes later, when agents start interacting with each other, with APIs, with wallets, with the entire digital economy. "Agents can not get a bank account. They do not have IDs. But they can get a wallet," William said. "X402 is coming. NAT.fun is going to be supporting not only APIs but CLIs and MCPs."
When agents transact at scale, they need rails that are permissionless, programmable, and open. That is crypto's long game. And The Block Runner has been calling it for three years.
Episode 307 is a snapshot of where the industry stands in March 2026. The Metaverse is consolidating. The SEC has drawn lines. Bitcoin's security debate is heating up quietly. A new class of independent builders is shipping tools nobody asked them to build, solving real problems in industries that have never touched crypto or AI.
This is what the early days of every important cycle look like. Noisy, confusing, full of grief and opportunity at the same time. The people who are still paying attention, still building, still showing up every week to think clearly about what is happening, they are the ones who will look back and say they were there when it mattered.
