The UK's Isambard-AI supercomputer, a significant component in Europe's technological ambitions, is housed within a black metal cage topped with razor wire, an image that starkly mirrors the physical barriers of Fortress Europe. This infrastructure, fitted with 5,400 Nvidia “superchips,” underscores a broader trend where advanced technology and corporate interests converge, potentially reinforcing the continent's border regime even as the European Union commits billions to develop the next generation of artificial intelligence models. The global race for technological prowess, now led by China's LineShine supercomputer, highlights a strategic focus on digital infrastructure that, while presented for innovation, carries profound implications for surveillance, control, and the exacerbation of climate-driven migration.
China's LineShine computer in Shenzhen has now outranked its US counterparts, becoming the world’s most powerful supercomputer. This marks the first time since 2017, the ninth year, that a Chinese computer has topped the Top500 rankings, a list often seen as a measure of a nation’s technological strength. The LineShine, making its debut on the list, operates entirely on conventional computer chips, or CPUs, rather than the graphics processors (GPUs) commonly used for AI. It requires approximately 42.2 megawatts of electricity to function. Scientists involved in the Top500 project reported that LineShine achieved 2.198 exaflops, capable of performing over 2 quintillion calculations per second.
The US government’s Lawrence Livermore National Laboratory in California now hosts El Capitan, ranking second, followed by two other US supercomputers. Germany’s Jupiter supercomputer has dropped to fifth place. These five machines are the only publicly verified exascale computers globally, with other top 10 machines located in Italy, Switzerland, and Japan. The UK has 11 machines on the list of 500, with Isambard-AI being the highest ranked at 11th, a drop of two places since the last ranking. Western Australia’s Setonix, ranked 86th, is the best performing of the four machines in Australia.
The Climate Cost of Digital Borders
One year ago, the EU unveiled a €20bn plan to construct sites equipped with vast supercomputers, aiming to develop the next generation of AI models and enable Europe to compete with leaders in the US and China. These planned AI “gigafactories” are intended to target “moonshot” innovations across sectors such as healthcare, biotech, industry, robotics, and scientific discovery. The EU strategy document indicates that while the best-performing AI factories currently utilize up to 25,000 advanced AI processors, a gigafactory would exceed 100,000 AI processors.
These power-hungry facilities demand immense amounts of electricity and require huge quantities of water for cooling. An EU official stated that these facilities should run “as much as possible” on a green energy supply, with plans for “recycling” water if it is used. However, campaigners have expressed fears that such power-hungry datacentres could undermine Europe’s climate ambitions. The escalating climate crisis, exacerbated by such energy demands, disproportionately impacts the Global South, driving forced migration that Europe’s border regime then criminalises. The EU's rhetoric of climate responsibility thus clashes with the practical implications of its technological race.
Technology of Exclusion
The investment in advanced AI and supercomputing capabilities, while framed as progress, raises critical questions about its potential application within the architecture of Fortress Europe. The development of sophisticated AI models can be leveraged for enhanced border surveillance, biometric identification systems, and predictive analytics used to track and deter migrants. The presence of a supercomputer like Isambard-AI, encased in a black metal cage topped with razor wire, serves as a stark symbol of how technological advancement can be intertwined with the logic of exclusion and control that defines Europe’s approach to migration. This technological arms race, driven by states and corporations like Nvidia, risks further entrenching the "migration industry" by providing new tools for the "deportation machine" and the criminalisation of movement across borders.
