Perhaps conferences made sense fifty years ago. We did not have internet, and the pollution was not as bad. Today, we can have effective virtual meetings, while the pollution has reached a level of crisis, see this moving talk by Greta_Thunberg. Moving to a system of virtual conferences is I believe a duty of every scientist. Doing so will cut the significant air travel emissions that come from shipping scientists across the world. To attend a climate summit in the USofA, Greta will sail across the Atlantic ocean on a zero emission boat.
We can keep everything the way it is, but simply give the talks online. This change doesn’t involve anybody higher up in the political ladder. It only involves us, the program chairs, the steering committees.
While we wait for that, we can begin by virtualizing the physical STOC/FOCS PC meetings, whose added value over a virtual meeting, if any, does not justify the cost; and by holding conferences where the center of mass is, instead of exotic places where one can combine the trip with a vacation at the expense of tax payers’ money and everybody’s health. And that is also why I put a bid to hold the 2021 Conference on Computational Complexity in Boston.
NSF panels, making decisions worth millions, routinely have virtual panelists (I was the last few times). So why do we insist on shipping scientists across the globe multiple times a year to give 15-minute talks which to most people are less useful than spending 20 minutes reading the paper on the arxiv?
