Ah ok, thank you. Now I get it. I was confused by (i) “Imagine the reporter could do perfect inference” and (ii) “the reporter could simply do the best inference it can in the human Bayes net (given its predicted video)”.
(i) I thought of this as that the reporter alone can do it, but what is actually meant is that with the use of the predictor model it can do it.
(ii) Somehow I thought that “given its predicted video” is the important modification here, where in fact the only change is to go from that the reporter can do perfect inference, to that it does the best inference that it can.
