I think you're completely misunderstanding the thrust of the article. This ability goes far beyond memorizing knowledge in one specialized area. These people go through hours (up to 8 at a time) of testing about the everyday mundane events that have happened as well as the extraordinary things - there is no way for them to trick their testers. In the 60 minute piece, they could recall amazing detail about days from 20 years ago. This goes far beyond memorizing weather patterns and reconstructing information according to the regularity of a work schedule, etc.

I think what a lot of people are noticing here is that this extraordinary ability has not been commensurate with extraordinary accomplishments and it leads them to downplay the significance...

I'm not saying their abilities aren't "extraordinary" or at least very impressive compared to what one might naively imagine. I am more saying that people who spend endorsement efforts in other areas also tend to gain enormous abilities and so these are "normal" extraordinary abilities.

The point others have raised about these people not having abilities in other areas goes beyond this "unique talent" "not transferring". The point is that the people with these "abilities" spend a fair portion of their waking hours maintaining them. The memories may be accurate but they're "honed", time is spent codifying them.

Most specifically, the memories are clearly very different anything "photographic".

Just consider, if a person actually a video tape of their entire life, using said tape to answer questions about "what happen on day X" would take a few hours of mental processing. These people answer such questions instantly.

They've made themselves "experts" on one subject, themselves, and the ability give instant answers on that subject is a clue to this...

'Just consider, if a person actually a video tape of their entire life, using said tape to answer questions about "what happen on day X" would take a few hours of mental processing.'

You're making a huge pile of unsupported assertions, but this is the most egregious. You have the outline of an interesting theory, but little more. For one thing I see no evidence that there is any conscious effort made to maintain these memories, in many cases the people express every desire not to have this happen, yet it happens anyhow. At the point where your "making themselves experts" happens at a purely automatic level and against their conscious will you've stretched the words beyond any reasonable meaning, and I'm not sure your theory can even in principle be converted into something that corresponds to the real world.

The article states that some of these people don't even want to remember everything - so there obviously are people who don't spend a lot of time exercising this skill but who simply have it.
