The world of technology is buzzing with the idea that the mighty data centre could soon be a thing of the past. But is it really possible that the humble smartphone will render these massive facilities obsolete? Perplexity CEO Aravind Srinivas recently sparked an intriguing discussion on a podcast, suggesting that powerful, personalized AI tools could run on the hardware already in our devices, rather than relying on remote data centres. This concept is not entirely new, as Apple's AI system, Apple Intelligence, already leverages specialized chips in its latest devices for faster processing and enhanced data security. Microsoft's Copilot+ laptops also incorporate on-device AI processing. However, these advancements are primarily found in premium-priced gadgets, and not many current devices possess this capability due to the extensive processing power required. While the data centre industry is thriving in terms of demand, the question remains: is it getting smaller in other ways? Data centres have traditionally been massive buildings housing powerful computers that perform various digital tasks, from video streaming and online banking to AI processing and data storage. However, there are intriguing examples of smaller data centres, such as a washing machine-sized facility in Devon, UK, which not only provides computing power but also heats a public swimming pool. Additionally, a British couple heated their home using a small data centre in their garden shed, and a university professor kept his office warm with a GPU under his desk. Despite these innovative examples, the tech industry is also investing billions in large-scale data centre plants worldwide, with around 100 new ones underway in the UK alone. The environmental impact of these energy-intensive facilities is a significant concern. However, some experts, like Mark Bjornsgaard, advocate for smaller 'edge' data centres near large populations, reducing latency and response times. Bjornsgaard believes that every public building should house a small data centre, working in a network when needed, and providing heating as a byproduct. Amanda Brock, the head of business organization OpenUK, shares this view, predicting that the data centre myth will eventually burst. She suggests repurposing derelict buildings and closed shops into small data centres. Looking further afield, space offers an opportunity to rethink data structure with small, scalable data centres in orbit, providing efficiency, performance, and flexibility, according to CEO of Ramon Space, Avi Shabtai. However, the proliferation of small data centres raises concerns about national security. Professor Alan Woodward from Surrey University, a computer security expert, argues that small targets have less impact if penetrated, and larger centres can be significant points of failure. The debate over the future of data centres is complex, and the tech sector is increasingly questioning the rationale behind housing everything in remote, massive data centres. As AI tools evolve, the trend towards smaller, more localized processing may become more prominent, potentially reducing the need for large-scale data centres. However, the counterargument is that small targets have less impact if compromised, and larger centres can be significant points of failure. The future of data centres remains uncertain, but one thing is clear: the landscape of technology is rapidly changing, and the concept of 'small is the new big' may just be the next big thing.
