It’s easy to get swept up in the futuristic possibilities of AI—AI-powered assistants writing novels, self-driving cars navigating busy cities, or algorithms diagnosing complex medical conditions. But beneath the surface lies a critical question: what’s happening under the hood, and are we heading in the right direction?
One concept that stands out is spiking neural networks (SNNs). This is a next-generation model inspired by how the human brain processes information. Unlike traditional artificial neural networks, which activate all neurons simultaneously in a brute-force style, spiking networks mimic the brain’s elegance. Neurons fire only when necessary, making them inherently more energy-efficient and scalable. As language models grow—with GPT-4, for instance, consuming massive computational resources—this approach feels unlikely to continue to scale.
Traditional AI models are like a room full of people shouting their ideas all at once, while spiking neural networks are a calm, orderly discussion where only the most relevant points are spoken aloud. This shift could redefine scalability and sustainability in AI development.
Spiking neural networks would bring us closer to bridging the gap between biology and technology. Our understanding of the brain is still evolving, and as neuroscience uncovers more about how biological neurons communicate, we have an opportunity to integrate these findings into AI systems. This alignment isn’t just about efficiency; it’s about unlocking entirely new possibilities. Could advances in AI help us uncover biological limitations and improve upon them? Could machines and humans co-create the next phase of intelligence?
These questions nudge us toward what might be call a new form of singularity—not the ominous “robots take over” narrative, but a collaborative evolution where biology and technology enhance one another.
If AI is to reach its full potential, we need to address a limitation that’s holding us back: the human-computer interface. Right now, our interactions with machines rely on screens, keyboards, and audio. These are clunky. As technology becomes more sophisticated, these interfaces will hit a natural ceiling. Direct brain-machine communication is the solution.
Brain-computer interfaces (BCIs) are rapidly becoming science fact. Imagine a future where we bypass physical inputs altogether, interfacing directly with AI at a neural level. For individuals with neurodegenerative conditions, this could be life-changing. For others, it could redefine what it means to collaborate with technology. We’re not just talking about convenience; we’re talking about augmenting human potential in ways we’ve never imagined.
Of course, with great power comes great responsibility—and AI ethics is one area where the stakes couldn’t be higher. Generative AI is a double-edged sword: while it offers immense potential, it also introduces risks like hallucinations, bias, and misuse. It’s common to hear about AI models producing false information or perpetuating harmful stereotypes. How do we minimise these risks?
One solution lies in context. Generative AI systems allow for adjustable settings like temperature, which controls how creative or prescriptive the output is. For safety-critical applications—like healthcare or autonomous vehicles—we can dial down the creativity and prioritise precision. But this only addresses part of the problem. Embedding ethical models into AI systems is a bigger challenge, not least because humanity itself struggles to agree on universal ethics. The trolley problem illustrates just how nuanced these decisions can be.
Consider autonomous vehicles. Should they prioritise the safety of passengers or pedestrians? What if the sensory input is ambiguous? These aren’t hypothetical questions; they’re real-world dilemmas that AI developers must confront. And while we can’t program perfect morality into machines, we can strive for transparency and accountability in the decision-making processes.
When it comes to regulating AI, I lean toward optimism. Collaboration between companies, governments, and individuals is essential, but I suspect existing governance structures may fall short. The pace of technological change demands something entirely new—a dynamic, adaptive framework that evolves alongside AI itself. Perhaps it’s time for global cooperation on a scale we’ve never attempted before.
So, where does this leave us? Should we focus on scaling what we already know, or take bigger risks to explore uncharted territory? I think we need to do both. Scaling existing architectures ensures short-term progress, while high-risk, high-reward research into new approaches—like spiking networks or advanced BCIs—lays the groundwork for the future.
If there’s one area where these advancements can truly shine, it’s healthcare. Brain-computer interfaces could revolutionise treatments for neurodegenerative conditions, enabling direct communication between patients and machines. Generative AI could support doctors with tailored insights, while spiking neural networks could power efficient, real-time decision-making in critical care scenarios. The possibilities are endless.
AI isn’t just the next generation of tools; it’s the next step in human evolution. By prioritising energy efficiency, ethical design, and bold exploration, we can build systems that don’t just solve problems but redefine what’s possible. Whether it’s through brain-computer interfaces, spiking networks, or entirely new paradigms, the future of AI lies in its ability to amplify human potential while respecting the delicate balance of ethics and innovation.
The question isn’t just what AI can do. It’s what we choose to do with it…
