The convergence of technology and global ageing is driving new business opportunities, innovations in service delivery and the promise of a better life tomorrow for older adults and those who care for them. Despite its promise, technology has a Janus face introducing both new solutions as well as new problems. Successful development and integration of technology as a tool to transform global ageing into global opportunity requires that individuals, families, business and governments, at all levels, address key trade-offs: functionality versus complexity; service versus stigma; universal design versus universally dull; safety versus privacy; health versus dignity; availability versus equity; and lastly, hightech versus high-touch.
