Isn't the problem precisely that uncertainty though? That we have many data points showing that a rotting banana skin will not spontaneously gain sentience, but we have no clear way to predict the future? And we have no way of knowing the true chance of superintelligence arising from the current path of AI research—the fact that it could be 1-in-100 or 1-in-1e12 or whatever is part of the discussion of uncertainty itself, and people are biased in all sorts of ways to believe that the true risk is somewhere on that continuum.
