It seems as if David Mumford is speaking at this conference I kinda plan to attend:
Some people are listed as giving virtual talks, but he's listed as giving a real talk. (The opposite of virtual.)
I don't know if I really believe that. But anyway, his talk title is "Grammars, feedback, high dimensional representation: clues to the magical algorithm", and since I've never met him, his presence might be enough to make me overcome my fear of COVID and go there.
Did you decide yet?
I see the talks from the first day are available online--I'm eager to watch the talk by Melanie Mitchell, whose name somehow rang a bell for me from reading "Fluid Concepts and Creative Analogies" a long time ago.
I'm going there tonight, a bit late, and I'll give my talk there tomorrow.
