Remote work, why not remote conferences too?

Climate change is reaching the media more and more, every day we hear more stories about the bad things caused by climate change and also the youth protests “Fridays for Future” are very popular (at least here in Germany and Europe). That is one side to it. On the other hand, I read on Twitter almost every day about conferences and developers all over the world who fly there just to listen to some presentations or give some themselves.
