Sam Altman believes that the ability to generate simulated worlds like those produced by Sora increases the probability that we live in a simulation, though it is not the strongest piece of evidence for this idea.
Does this increase your belief if you ever had one that we live in a simulation, maybe a simulated world generated by an AI system? - Yes, somewhat. I don't think that's like the strongest piece of evidence. I think the fact that we can generate worlds should increase everyone's probability somewhat or at least open to it, openness to it somewhat.
