Email from February 2024: https://81018.com/bbc/#Emails and https://81018.com/reformat/#Emails

Sometimes emails to key thinkers are not posted. These are people, if I could, I would have within my inner circle. Honest, direct, forthright… not afraid to be critical. There are several to whom I have been writing for many years. That list goes back to 2011 with Steve Curtis, Cathy Boucvalt, Bryce Estes; 2012 – Frank Wilczek, John Baez; 2013 – Giovanni Amelino-Camelia, Chuanming Zong; 2014 – Brian Josephson, Steven Strogatz; 2016 – George F. R. Ellis; 2017 – Anthony Aguirre, Stephon Alexander; 2019 – Espen Gaarder Haug, Ari Lehto; 2020 – Tim Palmer, Martin R. Bridson, Fotini Markopoulou, Edward Nouri Zalta; 2021 – Edward B. Burger, and Xijia Wang.

Of course, there are many others and many will eventually be included.
