Chomsky was doing so many podcasts up to the moment he disappeared from the radar presumably due to medical issues. I've seen him going for 2 hours with some nobody with 5K followers, being asked juvenile and stupid questions and answering with the patient of a Saint. He looked quite diminished physically, elderly and frail but mentally he's always sharp and his recall and memory is scary.
I feel that in his later years he made a conscious effort to talk to young people and made them aware of the history and depth of the problems the world is facing, and he used very modern avenues to do so, like podcast interviews. I will always have the highest degree of respect for this man and an admiration for his integrity, sensitivity and scholarship.
