The burgeoning progress of cutting-edge technology paradoxically evokes nostalgia. How does this emotion influence responses to innovative technology, such as Artificial Intelligence (AI)? We hypothesized that two pathways operate concurrently. First, by enhancing connection with significant others, nostalgia constitutes a psychological resource that supports exploration of technological innovation, thereby promoting positive responses to AI. Second, by reinforcing scepticism toward change, nostalgia heightens uncertainty about innovative technology, thereby fostering negative responses to AI. Three preregistered experiments, testing participants (ΣN = 1397) across cultures (China, UK, USA), supported the two pathways. Nostalgia influenced responses to ChatGPT via two opposing serial pathways (Experiment 1). Further, social connectedness bolstered favourable responses to AI avatars via increased technology exploration (Experiment 2), whereas scepticism about change reduced favourable responses to companion robots via increased technology uncertainty (Experiment 3). This dualistic role of nostalgia can be harnessed to sustain new technology or instill caution for its risks.
