It seems to me that viewing a late Great Filter to be worse news than an early Great Filter is another instance of the confusion and irrationality of SSA/SIA-style anthropic reasoning and subjective anticipation. If you anticipate anything, believing that the great filter is more likely to lie in the future means you have to anticipate a higher probability of experiencing doom.

Let's take this further: is there any reason, besides our obsession with subjective anticipation, to discuss whether a late great filter is 'good' or 'bad' news, over and above policy implications? Why would an idealized agent evaluate the utility of counterfactuals it knows it can't realize?
