How Hyper-Datafication Impacts the Sustainability Costs in Frontier AI Sophia N. Wilson, Sebastian Mair, Mophat Okinyi, Erik B. Dam, Janin Koch, Raghavendra Selvan https://arxiv.org/abs/2602.00056 #AI #thereIsNoAI #thereIsInParticularNoSustainableAI

How Hyper-Datafication Impacts the Sustainability Costs in Frontier AI

Large-scale data has fuelled the success of frontier artificial intelligence (AI) models over the past decade. This expansion has relied on sustained efforts by large technology corporations to aggregate and curate internet-scale datasets. In this work, we examine the environmental, social, and economic costs of large-scale data in AI through a sustainability lens. We argue that the field is shifting from building models from data to actively creating data for building models. We characterise this transition as hyper-datafication, which marks a critical juncture for the future of frontier AI and its societal impacts. To quantify and contextualise data-related costs, we analyse approximately 550,000 datasets from the Hugging Face Hub, focusing on dataset growth, storage-related energy consumption and carbon footprint, and societal representation using language data. We complement this analysis with qualitative responses from data workers in Kenya to examine the labour involved, including direct employment by big tech corporations and exposure to graphic content. We further draw on external data sources to substantiate our findings by illustrating the global disparity in data centre infrastructure. Our analyses reveal that hyper-datafication does not merely increase resource consumption but systematically redistributes environmental burdens, labour risks, and representational harms toward the Global South, precarious data workers, and under-represented cultures. Thus, we propose Data PROOFS recommendations spanning provenance, resource awareness, ownership, openness, frugality, and standards to mitigate these costs. Our work aims to make visible the often-overlooked costs of data that underpin frontier AI and to stimulate broader debate within the research community and beyond.

Many thanks for the invitation & discussions after!

Gør AI udviklere overflødige? Ikke ifølge ITU-professor Peter Sestoft og uddannelseschef Luís Cruz-Filipe. "Der er stadigvæk brug for ekstremt dygtige softwareudviklere, som kan styre de her AI‑agenter og bruge dem til at lave ordentligt software, som faktisk kan bruges ansvarligt." #dktech #itpol

In January, @anishathalye.bsky.social, @josejg.bsky.social, and I returned to @csail.mit.edu to teach Missing Semester, a class on topics we miss from most CS programs—tools and techniques that everyone should know, like Bash, Git, CI, and AI tools. Today, we’re releasing the course for free online!

MSc thesis work of Emil Houlborg and Andreas Tietgen @itu.dk will be presented at CIDR conference next week. Huge congrats to them! Modern storage I/O landscape is very diverse, yet not so accessible. We created a new file system extension for @duckdb.org with xNVMe to help with this accessibility.

Azim had a stellar committee which included Daniel Lemire (TELUQ 🇨🇦), Pinar Tözün (ITU 🇩🇰) and Viktor Leis (TUM 🇩🇪). They gave talks at the Dutch Seminar on Data Systems Design (DSDSD) on SIMD-accelerated parsing, xNVMe and escaping from the insanity of SQL. (video will be posted on dsdsd.da.cwi.nl)

Looking forward to the South Bay Systems event after CIDR on Jan 21! I will be presenting our CIDR'26 paper on integrating xNVMe into DuckDB --> vldb.org/cidrdb/paper... Thanks for the invitation @southbaysystems.xyz @alexmillerdb.bsky.social !!
