“When an old man dies, a library burns to the ground”, says an African quote. Older people are a source of information about “modern times a long time ago” and can share their experiences with younger generations. How was life 60 years ago? How to use a typewriter? How to age happy and fulfilled? How to find one’s way without a GPS and friends without Facebook? Homo analogis meets digital natives and engages in a lively exchange about science and technology, life and society. Two examples of intergenerational programmes are presented: “Dialogue with Time”, an exhibition where seniors over 70 work as mediators; and the workshop “Raconte-moi tes techniques” where old and young share their knowledge about objects of different times, demonstrating that science and technology can foster intergenerational dialogue.
