Sure, many people may be exactly like what the general impression is about what an autistic person is like, I am just saying that there many different flavors and abilities and experiences of autism.
my son does have extraordinary abilities in music, computers, and memory.
I guess the question is whether an expert would label that as a "savant" ability. I don't think "savant" is even very well defined. There are plenty of neurotypical (aka non-autistic) children with amazing talents. I personally have a tremendous memory for dates, numbers, words, and facts. I spent several years studying primary sources relating to historical urban geography pertaining to an area of about 16 city blocks. I absorbed huge amounts of data like names of business in these locations, what the buildings looked like, the dates when buildings were built and torn down, etc. spanning a period of 150 years. This allowed me to synthesize the data and visualize mentally what any location in that area looked like at any point during that time span. Today I can walk there and imagine how any spot used to look and see traces of the past. I was able to look at an undated photo and determine from looking at it the year the photo was taken, and sometimes, possibly the month. In 1994 I walked into an art gallery and an artist had done a massively researched painting of the harbor of this location and I told the gallery owner right off what year the painting was supposed to depict, but pointed out two anachronisms that the artist did not notice. In 2000, an architecture historian invited me on a three-hour walk of downtown with the "dean" of historical architecture and I ended up teaching him about the history more than he taught me. Is that a savant ability? I personally don't think so. Maybe I have gone into the wrong profession...I'd be a fantastic appraiser considering my attention to minute detail. But my memory is utterly the pits when it comes to auditory information. I am hopeless when it comes to instructions and directions given orally, for instance.
What's most disturbing is how common all these conditions have become!
My personal belief is that they are always been very common, just not recognized and labeled as such.
