Decemeber 6, 2022 Dear Nikola, Thank you for your e-mail. I very much hope that you will feel better soon. I have been somnolent and have spent much of the day sleeping. When I am awake, I try to read about quantum computing and quantum information theory, topics so obscure that I have no business even to try to understand them. I ask myself whether there is any virtue in trying to understand my inability to understand. Senile dementia takes many forms. EJM
