In scientific conferences, the talks are often the least constructive part of the meeting. That’s my experience and opinion, at least. This is ironic, because at least in theory, the talks are the raison d’être of a conference.
When people fly in from great distances to be together, should we really be spending most of the day in dark rooms listening to canned talks from our colleagues? Should we be spending our time on things that we could just as easily do in a webinar?
