A bunch of people have contacted me asking why some of my video channel content covers the same issues repeatedly. Just to clarify: I don't make *content* per se - I do almost nothing especially for the purpose of putting things online. All I do is hit Record when people ask me to give zoom talks to academic audiences, and on ~20% of the meetings I have with my collaborators and other academics as part of my attempt to improve our work. That's it; I put those things up on our Allen Center channel as a contribution to Open Science but I don't edit or produce anything special; I make no $ from clicks or followers or however all that works, I have no clue and no time to learn about it or to check how things land with the viewers. (although, I've now had assistance for which I am grateful from @adithyan_ai, @dineshsai, and @DNAMediaEditing who actually know how to make these things convenient for people to see). Anyway, my talks often cover similar material from different perspectives because 1) very different audiences invite me to speak and I can't assume they already know the basics 2) it often takes hearing this stuff many times before it makes sense and I'm constantly working on new delivery approaches - how to describe which things and in what order, so that the global vision becomes clearer to experts from different fields and to young scientists entering the research arena 3) science is difficult and slow, and massive advances (such that would be priorities for a 45min talk for example) don't come around every month 4) and, though the background and some of my favorite examples are often the same, each talk has *something* new because I'm adding things to them all the time.
