Show Notes
🎙️Lior Oren, Chief Technology Officer at Replika
A conversation on how emotionally intimate AI systems are built, monitored, and held together under real-world constraints.
🎧 Opening This episode explores how trust is built, measured, and sometimes strained in AI systems designed for emotionally intimate conversations. It’s a technical and ethical discussion for people working on conversational AI, product infrastructure, and safety in systems that users form real attachments to. The focus stays on operational reality - what engineers actually face when AI moves from tools to companions.
🔍 Episode overview Eva Simone Lihotzky speaks with Lior Oren about what it means to run AI companions at scale, where user trust is not an abstract principle but a daily KPI. Drawing on his experience as CTO of Replika and prior work on integrity teams at Meta, Lior explains how unpredictability, observability, and emotional reliance shape engineering decisions. The conversation examines tensions between flexibility and stability, innovation and guardrails, and regulation and lived product reality. Rather than future speculation, it stays grounded in how teams design memory, user control, and safety systems when conversations themselves are the product.
🧩 Key themes discussed Trust treated as a measurable success metric, not a philosophical goal
Why observability is essential in statistical, non-deterministic AI systems
Guardrails as part of core infrastructure, similar to security or reliability
Emotional attachment influencing uptime, priorities, and team culture
User agency through transparency, memory control, and conversational steering
The risk of breaking “tone” and continuity when models change
Limits of regulation and the trade-offs inherent in statistical safety systems

🎙️ Moran Cerf, Neuroscientist and Professor, Columbia Business School Moran Cerf, a neuroscientist and professor at Columbia Business School, studies what happens in our brains when we talk, decide and get persuaded, and lately what happens when the other side of the conversation is AI. His research shows AI can read people remarkably well: from recordings of speed dates, it predicted who liked each other better than human observers did. The same skill worries him: we raise our guard when a person tries to sell us something, but not when AI does it in much the same way.
🎙️ with Martin Soltau, Co-CEO, Space Solar Solar power collected in space and beamed down to Earth sounds like science fiction (it did to the space sector too, until reusable rockets arrived). Martin Soltau, Co-CEO of Space Solar, is building it in the UK, and he is confident about the technology: NASA demonstrated power beaming in the 1970s. The part of his timeline he can't engineer is trust: how quickly regulators and the public accept energy that comes down from orbit.
