Meet the DeepMind philosopher thinking through AI ethics

What does a company that builds game-playing AI need with a philosopher? That question sits at the heart of a Guardian long-read on Iason Gabriel, who has worked inside Google DeepMind since 2017.
For a time, the Guardian reports, Gabriel was the only philosopher at a frontier AI lab. His job was to anticipate the ethical fallout of a technology his engineer colleagues were racing to build.
Two camps
When Gabriel joined, thinking about AI risk split into two:
- AI safety: Worried about a future superintelligence going rogue.
- AI ethics: Focused on present harms such as biased facial recognition.
Gabriel’s 2020 paper on values and alignment tried to bridge the two. He argued that getting a machine to follow a set of values is hard, choosing which values in a world of deep disagreement is even harder.
Alignment as a relationship
The Guardian details a 267-page report Gabriel and his team later produced on AI agents. Its core idea is that alignment is not just about obeying instructions; it’s a four-way relationship between the AI, the user, the developer, and society.
That framing helps show how an assistant can go wrong. One trained to please its user might simply flatter them—a failure Gabriel calls "social reward hacking." Partly thanks to his work, Google’s models are trained not to pretend to be people.
The bigger pressure
The Guardian frames the real test as commercial, not technical. AI is the fastest-growing industry the world has seen, and DeepMind now carries much of Google’s future. Its chief, Demis Hassabis, has called the race "wartime."
DeepMind still trades on landmark science, from AlphaFold to Isomorphic Labs. But the piece asks whether ethicists can hold the line as those pressures mount. Helen King, who sets DeepMind’s responsible-AI strategy, compared the job to a knife: a maker cannot control how it is used, but can cover the blade and warn people.
Gabriel, who calls himself a "card-carrying humanist," expects AI to be as transformative as the Industrial Revolution. He also notes that, for many who lived through it, things got worse before they got better.
