I think what it really comes down to is just a superior short term memory.
For example, I can take any two digit number and calculate it to the fourth
power (albeit far more slowly and error prone). I notice that I can maintain
the algorithmic "ultra-fluidity" that he seems so proficient with in the
numbers, however, as the size of the data sets necessary to remember grow, I
have to continually "break" the ultra-fluid data manipulation in order to
mentally repeat the data sets so that they remains unambiguous. So not only
do we have to mentally implement the algorithm in such a way that the output
is incrementally built from some input, but also it is necessary to remember
the input and the output. The thing with savants, it appears, is that they
have some particularly mental balance, in such a way that they can maintain
the ultra-fluid flow of the mental algorithm, and the output and input can
be remembed entirely unambigiously, without constantly repeating themselves.
It sure would be nice to figure out how to do that, if it's not an
I don't believe it is an unchangeable quality, because I have noticed that
the ability for me to remember in such a manner is related to my particular
state of mind. But I won't get into that right now.
ps. apologies if the sl4ness is below the threshold
