to the real-time data input on viral and microscopic populations that inhabits it. The urban touch-less design, the multiple screens measuring temperature and displaying updates of daily cases, were the most prominent transformation of the public realm during the thickest part of the lockdown. The pandemic revealed our condition as vectors for transmission, of how microscopic life and information is attached to every trace of movement we make, and how any action has consequences. The next public space is defined by the constant sampling of its microscopic components, how by means of advances inAI supervised recognition and DNA barcoding it now becomes possible to model the bacterial and viral loads that inhabit public spaces alongside us. It is perhaps this the only way in which our living environments can respond to the huge levels of complexity disclosed from this microscopic reality.
