The growing number of older adults facing isolation, cognitive decline, and technological exclusion poses critical challenges for the design of inclusive digital systems. Despite increasing research interest in age-inclusive technology, requirements engineering (RE) methods remain largely inadequate for this vulnerable population due to cognitive, linguistic, ethical, and contextual mismatches. This paper identifies four key challenges in applying RE to older adults: variability in cognitive and linguistic capabilities, ethical and privacy risks, fragmented design guidelines, and inconsistencies in requirements elicitation processes. To address these issues, we propose a multidisciplinary, AI-guided framework with five interlinked components: a community-driven corpus, age-sensitive elicitation techniques, emotionally intelligent tools for requirement creation, ethical awareness indicators, and inclusive validation processes. Our vision aims to foster technologies that are accessible, respectful, emotionally resonant, and practically effective for aging users, bridging the gap between RE research and real-world systems that empower older adults.
