Kuhn is a treasure, and his CloserToTruth channel is probably my favorite YouTube channel. I came across it during the Covid-19 lockdown, which is when I discovered YT itself. I do not have a clear memory of watching Kuhn during his PBS years. What a parade of stellar guests Kuhn has interviewed over the years! Lots of them he has interviewed multiple times. Interviews with Steven Weinberg, Roger Penrose, Frank Wilczek, Sean Carroll, Ed Witten, Carlo Rovelli, Lee Smolin, Juan Maldacena, David Z Albert, Tim Maudlin and Paul Davies are among the many highlights that I have watched on that channel.
Kuhn himself is magnificent in his lifelong focus on the most important topics concerning the Universe and Consciousness, treating every guest with respect, clarifying and accepting any assumptions they make. The guests themselves are hugely knowledgeable in their field of expertise, and are great communicators, with the recent series of interviews Kuhn has done with Saul Perlmutter on the current state of prominent issues in cosmology being an example.
Kuhn is 80 years of age, and still as sharp as ever. I wish him long life and continued good health, but I do wonder what will become of his YT channel and website when he passes eventually. Most of my daily YT consumption over the past four and a half years has been videos about the ongoing war (now two major wars), but when that war ends in a year or two, I will go back to a steady diet of science and math related YT videos.
