Due to the intervention of the last few months, ideas about proximity to fellow human beings have changed considerably.

Those of us who relied on public transport to get around in big cities such as London are now grounded to a large extent, unless if we rely on the kindness of people we know who drive vehicles.

Meanwhile online communication and instant messaging have emerged in the foreground of social contact. What difference does it make whether a video conferencing call comes from thousands of miles away or from within the city we live in?

Local and global concerns are being profoundly affected by these changes. Access, connection and participation have the potential to evoke hitherto unimaginable scenarios as a result.

Is there any point in looking back wistfully or pining for the past?
