The Covid-19 pandemic highlighted a two-fold observation. On the one hand, our technological advance did not prevent us from being hit hard by the scourge. On the other hand, political decision-makers, business leaders and citizens spontaneously turned to technology to find solutions to the crisis. Salvage reflex or solutionism? While business was largely suspended, telework and the digital economy played a key role. However, the use of technology in the fight against the epidemic raised many questions. Difficulties encountered in the implementation of contact tracing applications, connected objects checking social distancing or self-diagnostic devices are just one example. Social acceptance and assiduous use of these tools are necessary for their effectiveness, but many are reluctant to use them.
