The Blue•Print Research Unit — directed by John A BrownPreliminary evidence review — 1 November 2026https://the-blue-print.com/research/data-centre-research/ John A Brown initiated the research question, proposed its geographical scope and directed successive revisions. He reviewed the presentation and limitations, requested source checks and determined the intended public purpose. He retains responsibility for the final publication decision. AI assisted with spelling, punctuation or grammar. AI helped identify gaps, improve clarity or organise material. AI drafted or rewrote passages from material and directions supplied by people. Substantial portions were generated by AI, then selected, reviewed and approved by people. Grok researched and drafted the initial report, tables and website files under John A Brown’s instructions. ChatGPT reviewed successive drafts, consulted cited sources, revised text and evidence records, and prepared the PHP website integration and technical checks. This is a preliminary review rather than a complete global census or investment audit. It distinguishes directory listings, capacity estimates, forecasts, commitments and reported costs. Source checks establish what cited publishers report; they do not independently verify underlying capacity, expenditure or commercial returns. External publications remain separately authored sources.
