Bringing together artistic and scientific modes of inquiry, Witness statements and the technologies of memory examines the impact that digital technologies have on the substance of truth and historical facts. Hosted as part of Heba Y. Amin and Anthony Downey's online symposium, which was held in conjunction with Amin's exhibition When I see the future, I close my eyes, Chapter I (curated by Downey for the Mosaic Rooms in 2020), the panel discussed the legacies of colonial power and command, regimes of memory, and the ex post facto constitution of evidence from online archives. Drawing upon the diverse backgrounds and experiences of the panellists, which included Helene Kazan (Oxford Brookes University), Naeem Mohaiemen (Columbia University), and Susan Schuppli (Goldsmiths, University of London), Heba Y. Amin (Staatliche Akademie der Bildenden Künste Stuttgart), and Anthony Downey (Birmingham City University), Witness statements and the technologies of memory sought to more fully understand the impact of digital archives on historical records and evidence-gathering. Against the backdrop of indiscriminate expurgations of online material, we observe how the evidentiary potential of digital archives is compromised by the commercial imperatives of social media networks, censorship, and state surveillance. Among the many questions that arise here, the extent to which personal recollections are often presented as virtual artefacts of memory – a technology of recall or a mnemo-technics in its own right – remains central to the debate about the future of memory in our post-digital age.
