The "atom" terminology is a bit confusing to me. Isn't an "atom" just another thought vector? If "sunglasses" + "smiles" = "smiling-while-wearing-sunglasses", then "sunglasses" and "smiling-while-wearing-sunglasses" are both just vectors. Is there a reason for the distinction? Also, if all thoughts can be described as vectors and linear combinations of vectors in "thought-space", I wonder what the axis represent and how many dimensions there are. Are all thoughts just a combination of 100 "unit thoughts"? Really interesting post!
