The Synthetic Self: Redefining the Human through Perception

As AI fuses with our senses, selfhood stretches beyond skin into devices, networks, and shared environments. AR overlays, neuroadaptive wearables, and responsive prosthetics redraw bodily boundaries; perception becomes distributed, agency negotiated. Memory turns machinic—lifelogged, recomposed, replayed—shifting identity from felt continuity to curated data. Emotion AI yields an “emotional co-self,” mirroring and modulating mood in therapeutic and everyday contexts. Avatars, filters, and digital twins make authenticity dynamic and plural. This chapter traces the extended mind becoming an extended self—and asks how autonomy, consent, and responsibility survive predictive, ambient co-perception. When machines sense with us, we don’t just augment humanity; we refactor it.
