Description

Data centres are a hot-button issue, but what do they actually do, and why are people worried? Felicity Lewis, Explainer editor, answers all your questions.

Summary

This reporting examines the physical infrastructure required to sustain the rapid expansion of frontier AI models, highlighting the shift toward massive compute clusters. The concentration of computational power represents a critical bottleneck for AI development and poses significant challenges for oversight of high-capability systems and their associated environmental impacts. Understanding the physical layer of the AI stack is increasingly relevant to global and Australian discussions on data sovereignty, energy security, and the regulation of large-scale compute resources that could facilitate catastrophic risk.
