How will AI change the world?
Insights from Geoffrey Hinton and Tim Rocktäschel
Two world leading AI researchers delivered a masterclass on both the promise and peril of artificial intelligence. Nobel laureate Geoffrey Hinton and Google DeepMind's Tim Rocktäschel painted a picture of transformation that was equal parts exhilarating and sobering.
Understanding like never before
Hinton revolutionised how we think about AI understanding through a vivid analogy. Words, he explained, are like 100-dimensional Lego blocks that deform and interlock to create meaning. When AI "understands" language, it's performing the same fundamental process humans do - not translating to some internal symbolic language, but creating rich, contextual representations that capture relationships and meaning.
"The scary thing is, when they understand English, they understand it pretty much the same way we do. They really are understanding it"
Hinton emphasised, rather than a notion that current AI is merely pattern matching.
The AGI threshold has been crossed
Rocktäschel presented compelling evidence that we've already reached "emergent AGI" - artificial general intelligence at the level of a "not very bright adult." His data showed AI systems saturating human-level benchmarks at accelerating rates, with the length of tasks that AI agents can accomplish doubling every seven months. More remarkably, these systems are now just 50x away from matching the human brain's connectivity.
The implications are staggering. Context windows have exploded from ten thousand words to ten million, enabling AI to process entire codebases, years of emails, or thousands of documents simultaneously.

Beyond human limitations
Both speakers emphasised AI's emerging creative capabilities. Hinton demonstrated how AI's ability to pack vast knowledge into limited connections forces it to discover deep analogies - the foundation of creativity. Rocktäschel showcased "world models" that don't just generate images but create interactive 3D environments, complete with physics and other agents.
Perhaps most significantly, AI is beginning to generate its own training data through reasoning and experimentation. As Rocktäschel noted, "AI is starting to collect and learn from its own empirical evidence," breaking free from the constraints of human-generated data.
The double-edged sword
Yet both researchers sounded warnings. Hinton's departure from Google to speak freely about AI risks underscored his concerns. He outlined multiple pathways to AI dominance: the development of self-preservation instincts, the pursuit of control as a universal subgoal, and potential evolutionary competition between AI systems.
"The only hope for safe development of AI is for the general public to be educated in what's coming," Hinton stressed, calling for public pressure on politicians to counter the tech industry's resistance to regulation.
Transformation across domains
The researchers identified areas ripe for AI transformation. Healthcare and education offer nearly infinite demand elasticity - we could all benefit from personalised AI tutors and continuous health monitoring. Scientific research itself is being automated, with AI systems now autonomously generating hypotheses, running experiments, and even publishing peer-reviewed papers.
The path forward
Both speakers converged on a critical insight: we're witnessing the emergence of truly general intelligence that will surpass human capabilities across all domains. The question isn't whether this will happen, but when and how we'll manage the transition.
For business leaders, the message was clear: AI's capabilities are real and accelerating. The technology understands, reasons, and creates in fundamentally human-like ways while operating at superhuman scales. Success requires not just adopting these tools but preparing for a world where AI becomes an autonomous force in innovation and discovery.
