The study documents growing disparities in access to supercomputing resources and AI expertise, which are increasingly concentrated in a small number of regions dominated by the United States and China.

Notes on verification

Verbatim match to the source paper's stated findings, confirmed in both arXiv preprint and peer-reviewed Nature Scientific Reports version. Broadly consistent with independent data on US/China compute dominance. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable | framework convergence=single on Top500 dataset used by the paper's own authors as proxy for national compute capacity (upstreams: Top500 supercomputer list dataset) — publishers independent, evidence may not be | kind=attributed eligibility=high]
