In 2025 Stuart J. Russell reveals he is Alex Bogdanov who discovered immortality after perfecting his count dracula blood transfusion therapy (which he later taught to Peter Thiel). Simultaneously he announces that he has reconciled symbolism with connectionism and achieved strong AI. He uses this technology to resurrect a perfect replica of Lenin from 1917, but without any memory of Bogdanov. Bognadov tries to befriend this new Lenin but no matter what he does or how many times he tries from scratch, Lenin rejects him in the end.
essentially this is the converse of Eternal Sunshine of the Spotless Mind
