With no need of selfish conquest to ensure their own survival, they would arrive here merely out of intellectual curiousity.
They would seek to understand the biology and culture of the human species and catalog other bioforms. They would also want to catalog the geological features of the planet.
Would Aspies be involved in this? The aliens might seek out the most logical, scientific, intelligent and unbiased of humans to serve as collaborators in their peaceful conquest of knowledge. In that case, Aspies would stand a good chance at being involved.
