While I wouldn’t endorse the 2.5 PB figure itself, I would caution against this line of argument. It’s possible for your brain to contain plenty of information that is not accessible to your memory. Indeed, we know of plenty of such cognitive systems in the brain whose algorithms are both sophisticated and inaccessible to any kind of introspection: locomotion and vision are two obvious examples.
It might be right, I don’t know. I’m just making a local counterargument without commenting on whether the 2.5 PB figure is right or not, hence the lack of endorsement. I don’t think we know enough about the brain to endorse any specific figure, though 2.5 PB could perhaps fall within some plausible range.

I do want to ask why don’t you think the 2.5 petabyte figure is right, exactly?
