I'm impressed by his coherence at 93. We should all hope to be so lucky.

I'm 68 right now. Feel like I'm 8, listening to these guys. When I grow up I wanna be like Dr. Penrose.

It’s honestly incredible how well Penrose can explain a concept at his age! Unreal human being.

What an extraordinary privilege it is to be able to hear a conversation between a Nobel laureate who not only continues to explore the frontiers of knowledge but does so in unconventional, not to say eccentric, ways, and an accomplished, seasoned theoretical physicist who is also one of the great science communicators of our time. It's fascinating to glimpse and even to feel the tensions in the physics community, and at the same time to appreciate how much confirmed and shared knowledge we have gained. I'm enlightened; I'm uplifted; and I'm grateful. Thank you both.

I’ll never forget watching Roger Penrose speak in person at University, he has always been a very eloquent speaker.

As an old person myself it's a delight to see someone with such a young, active, creative mind.

I miss my dad. Roger reminds me so much of him. Dad died with a brilliant mind at the age of 91, only because he wanted to be with his wife of 65 years. RIP mom and dad.

Reading The Emperor's New Mind as a young man caused me to go back to Uni and study physics. Prof Penrose directly changed my life for the better and he will always be my Prof.

You know it’s a legend when he says Feynman attended his talk, he took a course from Dirac, and that he personally talked to Hawking and Guth

Awe inspiring that this man at 90+ is still working on the hardest questions we currently have.
