This month, our team attended two very different industry gatherings — Semafor's Next 3 Billion summit and the Avalanche Summit — but both left us with the same big question: what happens when technology outpaces the systems built to support the people inside them?
At Next 3 Billion, the conversation centered on the disruption reshaping Africa's diamond economies. At Avalanche Summit, it was blockchain infrastructure and tokenization reshaping capital markets. Different industries, same throughline: transformative technology moves fast, and the communities and institutions built around the old model don't always have time to adjust.
Lab-Grown Diamonds: A Structural Shift, Not a Trend
Synthetic diamonds - mostly produced in China and India - now account for roughly one-fifth of the global diamond market, up from just 1% a decade ago. Industry analysts project the synthetic market will grow another 300% by 2034. As one jeweler put it plainly: for every 100 diamonds his company sells today, around 95 are synthetic — compared to almost entirely natural just five or six years ago.
The impact is most visible in Botswana, where diamonds are not just an export category but the backbone of public life. Between 2023 and 2025, Debswana's output dropped 39%, and revenue for the fiscal year ending this September is expected to come in at less than half the historical average. Debswana isn't only a mining company — it runs schools, hospitals, and game parks — so the cuts ripple far beyond mining payrolls. Nearly 20% of its staff have already been let go, in a country where unemployment stood above 27% in early 2024.
The human toll is where the numbers become real. One laid-off cutter and polisher, who spent 17 years in the industry, told reporters: "I have debts and I don't know how I am going to pay them... I was the breadwinner in a big family. Now I don't even know how to feed my own." A Botswana Diamond Workers Union chairperson described a broader shift toward precarity across the workforce: "Workers who remain employed are increasingly on short-term or temporary contracts... This makes it difficult for families to plan because they do not know whether contracts will be renewed."
South Africa tells a similar story. De Beers' two-year "pause" at its flagship Venetia mine sounds temporary — but as one labor representative noted, "To say you will temporarily close Venetia for two years leaves those employees basically unemployed not just for a period of two years but until they can find alternative employment." In legacy mining regions along South Africa's West Coast, the pattern has already played out once: "The companies come, they come to mine our grounds, they give the people work. At the end of the day, there's a period... when that period is over, they leave and the people don't have work anymore."
Smaller-scale, artisanal operations feel the squeeze differently but no less acutely. In Sierra Leone's Kono District, diamond mining remains the primary source of income for entire rural communities — even as lab-grown competition, priced roughly 70% below natural stones, erodes the margins those communities depend on.
In response, producer nations aren't standing still. Botswana, Angola, Namibia, South Africa, and Congo have agreed to pool 1% of annual diamond revenues into a global marketing campaign — led by the Natural Diamond Council — to reassert the value of natural stones.
But the ethical framing isn't as simple as "natural vs. synthetic." As one Namibian sustainability consultant challenged: "Are we supporting extractive systems that build communities — or just exporting profits in a new form?" — pointing out that most lab-grown diamonds are produced using coal-powered electricity in high-carbon economies, with no requirement to reinvest in local communities. It's a tension that echoes a warning Nelson Mandela issued back in 2006: that shunning mined diamonds could "result in the destabilization of African diamond-producing countries and, ultimately, their peoples."
Avalanche Summit: Building the Infrastructure for What Comes Next
If the diamond story is about technology disrupting an existing system, the Avalanche Summit was about technology trying to become the system — specifically, the infrastructure underlying how value moves, settles, and gets priced.
Chains built for real use cases, not speculation, are winning. One speaker put Avalanche's positioning succinctly: "Backend for real businesses." The panel consensus was that distribution — not technical superiority — is now the deciding factor for which chains survive. As one speaker framed it: "I do think chains that are brought in by actually anchoring to what is a very specific use case or business or user base that I'm trying to serve" will outlast generalist platforms starting from zero. Robinhood and Coinbase are already proving the model, building captive chains that push their existing user bases in rather than competing to acquire new ones.
The panel's forward-looking metric was blunt: by September 2027, the only number that will matter is cash flow generated within the ecosystem — not TVL, not stablecoin volume, both of which can be gamed.
Tokenized equities have a geography problem. One speaker didn't mince words: "My slightly cynical [take]: I don't think tokenized equities have really any beneficial thing to bring to US market participants." The real demand, panelists argued, comes from overseas retail investors who lack easy brokerage access — and even then, the model that's winning isn't the "purest" one. Native on-chain issuance may be philosophically correct, but licensed wrapper models (like Robinhood's) are gaining traction faster, because "I don't think they care as much about issuer consent for the thing to be issued... I think they just look at brand name like Coinbase or Robinhood or a securitized issuer and say, do I trust that brand name that's attached to that?"
Stablecoins are quietly becoming corporate treasury infrastructure. A live case study: Hyundai Card ran a proof-of-concept using USDT on Avalanche to move money between its US and Mexico entities — one transaction during banking hours, one outside them. The framing from Tether's team was ambitious: "We are looking for the stablecoins can make the next generation of global treasury infrastructure... it's basically making USDT this common settlement layer." And notably, the strategic instinct was to stay bottom-up, not top-down: "Everything that we see at the top level actually comes from the behavior of a guy in an emerging market, for instance."
The bigger bet: a unified ledger. In a separate panel, the vision got even more ambitious — collapsing Wall Street's role as intermediary entirely. As one panelist described it: "What we as an industry like the end game is all of this is on one ledger... What the markets end up looking a lot more like, in my opinion, is not like the big short, but it's DoorDash" — a single system of record where every stakeholder has a vertically integrated application, and friction disappears because "we need to eliminate the friction by vertically integrating their application and making it easy to read and write data."
The stakes of getting there, in the panelist's words: "In the future, if this works, everything changes. On the investor side, it's infinite custom portfolios. On the issuer side, it's consolidated, streamlined service providers." And the losers are explicitly named: "Those who are benefiting from the inefficiencies of the current system, they go away, they get demolished, and the benefit goes back to the user." The consumer pitch is simple: "Why do I have my cash sitting in the bank account earning like zero yield when it can be productive and then I can spend it?"
Even legacy infrastructure isn't safe from the reckoning. One panelist dismissed today's clearinghouses and depositories as relics: "That piece of infrastructure which was designed in the 70s to solve a problem we had back then... it is actually not necessary today." Wealth management got the same treatment: "[It] is extremely inefficient, requires people doing things for you and it doesn't scale well... they don't serve people with small amounts of money."
Prediction markets are becoming real risk infrastructure. In a separate conversation on prediction markets, the pitch was about precision, not gambling: "What we try and do with prediction markets at Kalshi is say, what's the risk that you've got? How can we generate a product for you that gives you either information or even better risk transfer around that." The examples ranged from the mundane — "We've got mom-and-pop style ice cream shops who are hedging the weather" — to the institutional: "What attracts someone like AQR to the table here is you're looking at hedging risks that you can't hedge... You're completing markets for states of the world people care about deeply but have no ability to price them, to judge them, or to hedge them."
The regulatory framing carried a warning drawn straight from crypto's own history: "If you look at the parallels here to the crypto market, everybody who sat there and waited for regulatory certainty just doesn't have a business anymore."And the single biggest fix, if one were possible: "If I could wave a magic wand... [it] would be in people's minds. The difference between a regulated onshore environment and an unregulated offshore environment."
The Common Thread
Whether it's a diamond miner in Botswana or a wealth manager on Wall Street, the pattern is the same: new technology doesn't ask permission before it disrupts the incumbents built around the old model. The question worth sitting with — for diamonds, for tokenization, for prediction markets — isn't whether disruption is coming. It's who gets a seat at the table while it happens, and who gets left standing outside it.
