As others have pointed out, this kind of ability is already an object of
study in psychology and neuroscience - but I would take issue with some
of the comments about it.
I think it is definitely relevant to SL4, because it gives us some
fascinating clues about what is happening in the human cognitive system,
and the more clues we have, the more likely we will be able to build an AGI.
Second, there is some talk of Kim Peek's problem being the lack of a
relevance filter. The problem with this is that, as a theory of what is
going on, it is much too simple. There is an old analogy between a
radio circuit and a brain that illustrates the point: if you stick a
screwdriver into the back of a radio and take out a random component,
you are quite likely to get a radio that just sits there and makes a
squealing sound. Deduction: you just knocked out the "squeal
suppressor"......? Much too simplistic. Same with savant abilities
like those of Kim Peek: its just a missing "relevance filter"? Well,
that is a possible explanation, but I really, really doubt that it will
turn out to be that crude.
Daniel Tammet's ability to multiply seems to be mediated by a
shape-memory pathway. My (admittedly vague) guess would be that he
somehow got the shape memory part of his system to encode the math
algorithms for multiplication, so that he can feed in the numbers as
shapes and get them back as a new shape, corresponding to the product.
I would be interested to know what he has been doing all these years,
and whether he can perform many other types of mathematical operations.
