I found a new style of conference management in a field of computer science in England. That is a conference named "BIAS 2022", that discusses topics of algorithm in a set of two distinctive parts of a conference: one is a face-to-face style and another is a virtual one. You can take part in both of either by buying two tickets or a single ticket for the conference. The ticket fee is different from each other. I love this idea, because the virtual conference is apparently different from the conventional style of face-to-face meeting. Particularly, social involvement in community is the deeper in in-person attendance. And, an amount of information that you can gather is the larger, too. The year of 2022 would become an epoch making year for conference management.
