Be My Guest! is a collective mixed-reality dinner event hosted by AI. The installation rethinks an age-old gathering ritual: a dinner with friends, where AI, named Parasite, becomes the host and co-creator of the physical stage. The collective experience transforms the private setting of home into a public domain, mirroring our current condition of dwelling in multiple realities due to our constant connection through digital devices, investigating how we inhabit and interact within networked virtual spaces, and how we foster parasitic relationships with AI systems, redefining the fabric of communal gathering in the digital age. What happens when species meet?
