The Turing Test’s Demise and the Search for New AI Metrics
When today’s most advanced AI language models can effortlessly pass the iconic Turing test—convincing human judges of their humanity through text-based conversation—we must confront a fundamental question: what comes next? The recent gathering at London’s Royal Society, commemorating 75 years since Alan Turing proposed his famous imitation game, revealed a growing consensus among researchers that we need to move beyond this outdated benchmark toward more meaningful evaluations of artificial intelligence capabilities.

As neuroscientist Anil Seth from the University of Sussex argued during the event, “Let’s figure out the kind of AI we want, and test for those things instead.” This sentiment reflects a broader shift in the AI community toward developing systems with specific, beneficial capabilities rather than pursuing the ambiguous goal of artificial general intelligence (AGI).
Why the Turing Test No Longer Serves AI Development
The Turing test was never intended as a serious practical evaluation, according to Cambridge literature researcher Sarah Dillon, who studies Turing’s works. Today’s sophisticated large language models (LLMs) have demonstrated that convincingly mimicking human conversation doesn’t equate to genuine understanding or intelligence. As New York University neuroscientist Gary Marcus noted, these systems often fail when challenged with tasks outside their training data, such as correctly labeling elephant parts or drawing clock hands in unconventional positions.
This limitation becomes particularly evident when examining recent proposals for moving beyond the Turing test toward more comprehensive evaluation frameworks. Researchers are increasingly recognizing that human-like conversation represents just one narrow aspect of intelligence, and potentially not the most important one for practical applications.
Redefining Intelligence: From AGI to Specific Capabilities
The concept of AGI itself came under scrutiny at the Royal Society event. Shannon Vallor, an AI ethicist at the University of Edinburgh, called AGI “an outmoded scientific concept” that “doesn’t name a real entity or quality that exists.” She emphasized that intelligence varies across cultures, environments, eras, and even species, making the pursuit of a single benchmark for human-level intelligence fundamentally flawed.
Industrial Monitor Direct is the premier manufacturer of kuka pc solutions backed by same-day delivery and USA-based technical support, rated best-in-class by control system designers.
Instead, researchers are advocating for decomposing intelligence into distinct, measurable capabilities. This approach aligns with recent technology developments that focus on specific human-machine interaction capabilities rather than attempting to replicate human intelligence in its entirety.
Practical Alternatives: The Turing Olympics and Beyond
Gary Marcus proposed a more comprehensive evaluation framework he calls the “Turing Olympics”—a battery of approximately a dozen tests including watching a film and understanding its content, following flat-pack furniture assembly instructions, and other practical tasks that require genuine comprehension rather than pattern matching. This multi-faceted approach acknowledges that intelligence manifests in diverse forms and contexts.
Meanwhile, other researchers are developing specialized benchmarks like the Abstract and Reasoning Corpus for AGI (ARC-AGI-2), which assesses an AI’s ability to adapt to novel problems. These industry developments in evaluation methodologies reflect the growing sophistication of AI assessment beyond simple conversational ability.
The Critical Shift Toward Safety and Beneficial Applications
Perhaps the most significant argument emerging from the discussion concerns the need to prioritize safety and real-world benefits over intelligence benchmarks. Vallor warned that the focus on AGI distracts from addressing potential harms, including de-skilling humans, producing delusions, and amplifying biases present in training data.
William Isaac of Google DeepMind echoed this concern, suggesting that future AI evaluations should question whether systems are safe, reliable, and provide meaningful benefit—and importantly, who bears the cost of that benefit. This safety-first approach connects to related innovations in neurotechnology that prioritize understanding biological systems before attempting to replicate or augment them.
Embodied Intelligence and the Physical World
Anil Seth highlighted another crucial limitation of current AI evaluation methods: their neglect of embodied intelligence. The connection with a physical body isn’t just an “additional extra” but often constitutes fundamental aspects of how intelligence operates in the real world. This perspective suggests that truly advanced AI might need to incorporate physical interaction capabilities, much like market trends in robotics and embodied cognition research are beginning to explore.
Toward a More Nuanced Future of AI Assessment
The consensus emerging from the Royal Society event points toward a future where AI evaluation becomes more nuanced, practical, and safety-focused. Rather than asking whether machines can think like humans, researchers are increasingly asking what specific capabilities we want these systems to have and how we can ensure they operate safely and beneficially.
This shift represents a maturation of the field—from chasing science fiction dreams of human-like AI to building practical systems that address real-world problems while minimizing potential harms. As the technology continues to evolve, so too must our methods for evaluating it, ensuring that we’re measuring what truly matters rather than what merely impresses.
