It seems to me that a form of modal realism and a strong version of the Simulation Hypothesis (not just a large fraction of all observer-moments in apparently pre-Singularity civilizations are simulated, but a large fraction of all observer-moments period) are substantially more likely than not. Others whom I respect emphasize the extent of our current confusion about anthropics, etc, so I assign a lower probability than I would based only on my impression, but I haven't fully exchanged private info.
