We have the pleasure to chat with Ola Michalec, a Senior Research Associate at University of Bristol. Don't miss on our discussion with Ola in 2020.For decades, nuclear plants, power stations, or wastewater facilities were safe from the hype of digital innovations. These industries have traditionally been operated by industrial control systems fairly simple computers using binary logics to enable the movement and sensing of engineering machinery. Such technologies were disconnected from the internet and operated on-site by manual workers. With the advent of the Fourth Industrial Revolution (Schilin, 2020) engineering processes are about to gain sophisticated computing capabilities, from remote control enabled by the cloud or predictive maintenance thanks to ML algorithms. Moreover, industry experts (Cisco, 2018) have already announced that modern computing is blending with legacy engineering technologies. But who is doing the blending and revolutionising? Drawing from the approaches in STS and Computer-Supported-Cooperative Work (Slayton and Clark-Ginsberg, 2018; Jenkins et al., 2020), our research looks at the collaborative practices between engineers and software workers (Michalec et al., 2020; Michalec et al, 2021). Based on the case study of the implementation of cyber security regulations in critical infrastructures, we investigate how practitioners navigate tensions between the priorities of modern computing (security, connectivity, innovations, interoperability) and traditional engineering (safety, reliability, availability). Ultimately, we argue that digital innovations entering the world of critical infrastructures will reconfigure the responsibilities and training needs for engineers to come. This, in turn, creates novel ethical and political considerations for the profession, which should inform the future STS research agenda.This episode is a live recording from Hacking Everything.
