Conferences are a great platform to exchange ideas and to learn about different research areas. Also, more importantly, conferences expedite the process of publishing as journals may take months/years.
However, my question is - "why was is it mandatory to attend a conference in person in order to publish a paper in some xyz conference in pre-pandemic times?"
There are many people constrained by factors like money/time/family and struggle to attend conferences. They do prefer publishing their results at a conference in order to expedite the process of publishing but find it extremely difficult to travel to a foreign country. Conferences are conducted in extremely extravagant venues and attending just lectures costs 500+ euros, leave aside food and stay. Conferences are often held in big cities so lodging is also tough. Travelling to remote countries is not only expensive but also has a large environmental and climate footprint.
In order to grow in academia, it is important to publish fast. But why does research publishing forces constraints like this, and why nobody talks against this? Why cannot there be choice given to authors to not visit if there are other constraints.
Will post-pandemic era be different even slightly different, and will we be inspired by the online system of conference existing in current times.
