The late Nobel-Prize-winning physicist and idiosyncratic Richard Feynman also said something similar to the quote attributed to Arram Sabeti below.
I do not believe that Feynman was explicitly named, or had any lines, in the movie “Opennheimer,” but you can see his character in the background of one scene playing the bongo drums. Perhaps he was eccentric, but I liked his views on methodology and his unpretentious, optimistic, and straightforward spirit.
(p. 9) As the longevity entrepreneur Arram Sabeti told The New Yorker: “The proposition that we can live forever is obvious. It doesn’t violate the laws of physics, so we can achieve it.”
