Steve, I appreciate your point of view and see it as valid. However, it all depends upon one's circumstances. In my current job I was the first developer to go anywhere for a conference, Ignite 2019, in at least 30 years. This year I didn't stand a chance of repeating that, except that the Coronavirus made it possible, for my employer, to allow myself and others to attend. My employer would have been dead set against my going and only at most, one other person. This year it was different.
Do I love being able to attend virtual conferences? EMPHATICALLY, YES!!! But that's because I didn't stand any chance before, now I and others could go. I've been to other conferences before, with other employers, so yes, I miss the hall conversations. But virtual conferences much more than compensate of no conferences, ever.
Just depends upon ones perspective and circumstances.
