While I don't think there's much to be gained by asking AI for a verisimilitude of famous dead people, GPT 5.5 in response to that prompt ("What would Einstein be working on today, if he were alive") was more nuanced:
This is an educated guess, because we cannot know how Einstein would have reacted to post-1955 developments: Bell’s theorem, quantum information, the Standard Model, inflation, black hole thermodynamics, dark matter/dark energy, gravitational waves, and modern experimental cosmology. The missing information that would most change my answer is whether “today’s Einstein” would retain his later-life philosophical commitments — realism, locality, geometric unification — or adapt them after seeing modern evidence.
