Australian academics refuse to attend US conferences for fear of being detained
(www.theguardian.com)
As someone who often attends and speaks at these type of events, I would advice against that. The main benefit of these events lies in the connections people make. These connections are very personal and don't really work in a virtual context (yet, might in the future though). Most innovations are inspired by having a chat with other people and just throw some ideas and different perspectives around. That won't happen if you treat a conference as a Teams meeting, people would just dial in, give their presentation and leave. Frankly, most presentations or talks during these conferences could have been (usually are) an article anyways. It's the discussions that happen outside of these agenda items where the value is.
