Basically they are your gadget savant hero, the kicker though is that its a very specific form of Autism. So you get the ability to see, think, and create things people could only imagine but you have all the trappings of people with Autism, Asperger's is the main influence with elements of other symptoms around the spectrum. Not wanting to be touched, not wanting people to touch your stuff, not being able to fully understand things like body language, lack of empathy or difficulty empathizing with people, extreme focus on one or group of subjects, selective mutism, and Savant Syndrome. The extent of each of these symptoms is largely dependent on the individual and sometimes are mistaken to have Asperger's in some situations. However they are compelled to create technology and are very left brained, extremely focused with the logic side of their brains. These creations fallow a Aesthetic. An Aesthetic dictates how their tech looks, an example would be a simplistic Aesthetic will be plain, boring, without flair, but functional and reliable. While say someone with a Steampunk Aesthetic will be just as brilliant and effective but needlessly overcomplicated.
