What ethical responsibilities might we have towards potential future simulated beings if we achieve the capacity to create them?

If the Simulation Hypothesis is true, it suggests that our own existence could be contingent on the ethical decisions of a higher civilization. This raises a crucial question: if we develop the technology to create highly realistic, conscious simulations, what moral obligations do we have to their inhabitants? Should we ensure their well-being, freedom, or even awareness of their simulated nature? This thought process can inform our discussions around AI rights, virtual reality ethics, and the responsible development of advanced technologies.
