I kinda disagree. Even though I absolute loath the networking part of conferences, I came to hate online conferences even more. Listening to researchers with terrible microphones (because who is going to spend money on it if you use it once in a blue moon) is really not worth it.
Poster sessions are even worse. I was sitting in my private zoom call to present my poster, one or two persons dropped in, didn’t react when I asked if I should give them the spiel, and then just left.
Online conferences for me concentrate all of the negative aspects with none of the fun parts.
