Episode overview:

Natasha Blycha's path into emerging technology law started in an unlikely place. As a gap-year volunteer teaching English and economics at a school outside Gweru, Zimbabwe, circa 2000, she was simultaneously working for a small rural law firm on constitutional questions — an experience she credits with shaping the questions that have driven her career since.

In conversation with Andile Masuku, Blycha — who co-authored the Oxford Smart Legal Contracts textbook and was named the Financial Times' Most Innovative Lawyer — traces a line from those early days to advising global banks on whether their crypto experiments were even legal, to building LexChip: technology that embeds enforceable contracts directly into AI-powered devices.

The conversation spans smart contracts (the technical kind and the legally binding kind — they're different), why crypto adoption in Nigeria and Ghana has less to do with speculation and more to do with broken banking infrastructure, and what Jensen Huang's "five-layer AI cake" means for nations trying to build sovereign AI stacks without the energy, chips, or legal infrastructure to hold them together.

Blycha's central argument: if we can't put code in jail, and AI systems are becoming economic stakeholders that can book a million flights or displace entire workforces, then the law as currently designed has a problem. Her proposed contribution — smart legal contracts that act as referees inside AI systems, capable of stopping a device when it breaches its own rules — sits at the intersection of contract law and responsible AI.

Key insights:

• On why this isn't Y2K: "This is so much more complicated, so much more geopolitically complicated. And if we said that Y2K didn't happen, it was one day we got to find out. What we're seeing already with AI systems is we're already getting the proof in the pudding that they are working." Blycha argues Y2K was a manageable vector of complexity compared to AI. The difference: AI systems are actively delivering on their promise, and big tech's mandate to reach AGI means we can't simply wait for one day to find out.
• On why Africa's slower adoption might be an advantage, not a liability: "If I cannot keep the power on, am I really talking about agentic AI?" But Blycha points to a counterintuitive upside: countries without legacy infrastructure can leapfrog, just as India and parts of Africa bypassed landlines for mobile. Crypto adoption in Nigeria and Ghana demonstrates this — populations using blockchain not as a speculative instrument but as functional money in economies where traditional banking fails them.
• On the difference between smart contracts and smart legal contracts: A smart contract is code that executes on a blockchain — "if this happens, do this." It's a technical term, not a legal one. A smart legal contract, by contrast, is a real, enforceable agreement where specific clauses are automated. Blycha uses the example of a lease where rent adjusts automatically based on CPI. The distinction matters because conflating the two obscures where legal accountability actually sits.
• On the fundamental legal problem AI creates: "The law needs a person to ascribe responsibility to." Bitcoin was invented by someone who may not exist. Decentralised autonomous organisations insist the code is responsible, not them. But you can't put code in jail. As AI agents proliferate — booking flights, managing finances, making hiring decisions — the gap between what the technology does and who the law can hold accountable is widening faster than regulators can respond.
• On smart legal contracts as AI's conscience: Through LexChip, Blycha's team is embedding contracts directly into AI edge devices — robotics, autonomous vehicles, hardware with embodied AI. These contracts can monitor behaviour in real time and, critically, act as a referee: stopping a device safely when it breaches its rules. "You've taken an analog thing, you've turned it into a performance-based contract and it can speak to an AI system."
• On Ubuntu as an AI governance framework — with a warning: Blycha was moved by the Ubuntu principle of interconnectedness during a family visit to South Africa. She sees it as a potentially powerful ethical framework for AI policy — but cautions against using it as "window dressing for someone to write a wishy-washy policy that then doesn't deal with the hard stuff." The hard stuff: GPU clusters, cloud compute, sovereign data infrastructure. Values without investment are just declarations.
• On who opposes all of this — and why: Peter Thiel and a portion of Silicon Valley divide the world into accelerators and decelerators. In their framing, lawyers like Blycha are slowing down progress toward a post-human, transhumanist future of brain-computer interfaces and infinite lifespan. Blycha's response: "This is not a lawyers versus the tech bros conversation because there is an extremely large majority of the tech bros who are also saying there is a big problem here."

Notable moments:

1. The first text message: At the Bata Club in Gweru, Zimbabwe, circa 2000 — a social venue attached to a Canadian shoe factory — Blycha saw her first SMS travel between England and Zimbabwe on a feature phone. "It wasn't a smartphone, it was a dead phone." She'd bought her flight to Zimbabwe on the day of the Y2K bug because tickets were cheap. That moment — witnessing a communication revolution in a country experiencing currency crisis and fuel shortages — frames the conversation's central question about technology adoption in constrained environments.

2. The Mennonite test: Visiting Amish communities in Ohio, Blycha learned their approach to technology adoption. "They don't prohibit technology at all. They ask two questions: does this technology bring me closer to my family and does this technology bring me closer to God?" Asked how everyday people should think about adopting AI tools, Blycha offered this as her "heart answer" — a striking conclusion from someone who has spent her career at technology's legal frontier.

3. The McKinsey displacement reality: Blycha points to McKinsey's replacement of significant portions of its workforce with AI agents as evidence that displacement is not theoretical. The legal question this raises: how do you write an employment contract with an AI agent? And when that agent — operating at a scale no human can oversee — breaches the law, the "human in the loop" principle that underpins every AI governance framework starts to break down.
