I'm helping with facilitation of a conference today. The conference is in a hotel near Mount Kenya - 6,800km away from me. I'm sitting looking at an empty room on Zoom - they've gone for lunch - and marvelling at how in my lifetime we've gone from ARPANET to NSFNET and JANET to thinking nothing of being virtually present with people halfway round the earth, collaborating on the same information at the same time. We achieve so much when we collaborate. And we stand to lose so much if we don't.
