Ephemeral Communication Infrastructure and the Return to Oral Epistemology

This paper proposes that the dominant architecture of digital communication, in which the system functions as the primary site of memory and every conversation leaves a persistent trace in infrastructure not controlled by the speakers, is a recent and culturally specific arrangement rather than a structural necessity. It argues that pre-literate communicative architectures, including the oral traditions of Akan and broader West African cultures, operated on a fundamentally different principle: the recipient was the only archive. Words lived in the listener, and then, with the listener's memory and mortality, they faded. This was not a deficiency but a design with particular epistemic, ethical, and political virtues, virtues whose absence from contemporary digital communication has produced the surveillance, leakage, and chilling effects that now define the institutional communications crisis. The paper develops the concept of the recipient as archive as both a historical claim and an architectural principle. It draws on three bodies of scholarship: the foundational orality and literacy literature (Ong, Havelock, Goody); the Akan and broader African philosophical tradition on personhood, speech, and community (Danquah, Mbiti, Gyekye, Wiredu, Appiah, Ngũgĩ, Mbembe); and contemporary work on cryptographic ethics, privacy architecture, and digital sovereignty in Africa (Nissenbaum, Solove, Schneier, Rogaway, the African Union's Malabo Convention). The paper presents Piqabu, an ephemeral communication infrastructure designed for institutional use in West Africa, as a deliberate engineering attempt to instantiate the recipient-as-archive principle within digital systems. It argues that Piqabu is best understood not as a privacy feature or a security tool but as the first technical rung of a longer civilisational return: a return to a communicative arrangement in which the persistence of speech is not the default. The paper closes by arguing that this trajectory has a coherent endpoint. If recipient-as-archive is the architectural principle, then communication infrastructure in which there is no intermediary store at all, that is, infrastructure in which the recipient is structurally the only archive, is the trajectory's logical conclusion. This is the architectural definition of telepathy, and naming the trajectory in these terms clarifies both the engineering and the ethics of the present moment.
