Have there been any surveys asking experts when they expect superintelligence, rather than asking about HLMI? I'd be curious to see the results of such a survey, asking about time until "machine intelligence that greatly surpasses the performance of every human in most professions" as FHI's followup question put it, or similar. Since people indicated that they expected a fairly significant gap between HLMI and superintelligence, that would imply that the results of such a survey (asking only about superintelligence) should give longer time estimates, but I wouldn't be surprised if the results ended up giving very similar time estimates to the surveys about time until HLMI.
