The misuse of social media, the ethical challenges of artificial intelligence, and the urgent need for governance in the digital sphere were the key themes discussed at the London Tech Expo in the London Docklands today.
Speakers including Baroness Martha Lane Fox, documentary maker Louis Theroux and mathematician Professor Hannah Fry warned that anonymity, algorithmic amplification, and unmoderated engagement have reshaped human behaviour in ways that reward spectacle over empathy and extremity over nuance, with consequences for both individuals and society.
Lane Fox, entrepreneur and co-founder of Lastminute.com, called for more deliberate oversight of digital platforms.
“For too long, we have assumed the market would self-correct,” she said. She urged stronger privacy protections, robust age-assurance mechanisms for young users, and greater diversity in technology leadership.
“Underrepresentation of women and minority groups has real consequences for product design, algorithmic fairness, and the distribution of digital power,” she added, framing the discussion around accountability, ethics, and inclusion.
Lane Fox argued that leaving innovation entirely to commercial platforms has exposed society to systemic risks. From amplified disinformation to the monetisation of human attention, she said, the current trajectory prioritises engagement over societal well-being.
“We have the opportunity to build a digital ecosystem that protects users, promotes inclusion, and ensures accountability,” she warned. “It will not happen automatically; it will require deliberate choices by regulators, industry, and society.”
Louis Theroux illustrated the human consequences of social media’s reach. “You can fart in your front room, and millions of people are watching,” he said, referring to platforms such as X (formerly Twitter). “There’s no barrier to entry, and that’s a disaster.”
He emphasised the scale of amplification: “You stand in your kitchen at the door and end up with tens of thousands or even millions of followers. Of course a lot of them are bots. But they’re out there waiting on your every word.”
For Theroux, the digital world has collapsed the distance between private life and public exposure, leaving ordinary users vulnerable to magnification and misinterpretation.
Professor Hannah Fry, the mathematician and author, explained how the architecture of social media amplifies human impulses.
“It’s not that people are innately extreme. It’s that the system rewards extremity. Amplification becomes a vector for vulnerability,” she said. Fry described the permanence of content online, recounting how children can accidentally broadcast private images to millions. “We are designing systems that collapse privacy and reward impulsivity. A single click can put something online forever,” she said.
Theroux also explored the gendered and social dynamics of online engagement – something he explores in depth in his Netflix series Louis Theroux: Inside the Manosphere where he interviews anti-feminist influencers.
“What you come to realise is actually, in many respects, the most there is a projection of weakness rather than strength. It’s a compensation for a world that seems intimidating, for which many men feel lost. It’s a strategy for survival.”
Male-dominated content often emphasises aggression and bravado, while female creators may focus on social or reflective interactions, he said. Algorithms, however, reward extremes in both cases, producing distorted mirrors of human behaviour.
Fry, who recently recorded her own BBC documentary, AI Confidential With Hannah Fry, described encounters with developers creating avatars of deceased loved ones, designed to allow ongoing interaction.
“There’s a real human need here, but it is intertwined with exploitation. We need to be thoughtful about what is being monetised and scaled,” she said.
She emphasised that while AI can provide comfort and assistance, it cannot replace human judgment, creativity, or ethical reasoning. “AI can simplify tasks, but it cannot generate the insights that define human progress. Our challenge is to use these tools wisely, not to be dominated by them.”
Fry also addressed the financial incentives behind extreme content. “Engagement dictates how much money they make,” she said, referring to lightly curated, continuously streamed content optimised to maximise visibility. “In a sense, it’s like turbo-charging those impulses to perform your worst qualities.” The algorithms reward spectacle and provocation, not authenticity.
Despite these warnings, Fry offered a cautiously optimistic perspective. AI and social media can facilitate connection, creativity, and societal improvement—but only if deployed thoughtfully. “Ultimately, we can design systems that improve well-being and societal outcomes. But it will take vigilance, not passivity,” she said.
