You can usually come up with an explanation for why you did something.  You don&#x27;t have to &quot;get to the bottom&quot; of your own thought processes to do this: you just need to be able to reconstruct the symbolic manipulation part.  This seems like a good thing for an AI to be able to do -- <i>especially</i> a truly &quot;hard&quot; AI that you&#x27;d trust to run things at a high level.
