Teredo Expansion is a performative lecture delivered by the character of Charline L'hôtalière, fictional founder of the start-up "Teredo Expansion, ars longa, vita brevis". Facing an assembly of art student·exs about to graduate, she delivers an investment pitch: her company proposes to capture, extract and rebore the galleries carved by the Teredo navalis, a bivalve mollusc known for having caused the shipwreck of the Santa María of Chris in 1492, in order to protect the yachts of their near future. Behind an entrepreneurial discourse and its breviary of success unfolds a critique of the institutional neutralisation of critical discourse. The teredo, an organism that bores from within without destroying the surface, figures decolonial thought: a force of slow fragmentation that the institution hastens to capture, extract and rebore. The performance unfolds within a dispositif combining a PowerPoint presentation, ceramic teredo sculptures in aquariums, and objects distributed to the audience (certificate, membership form, sweets).
