Re: Space elephants
Why go so far. The ones here in Asia are pretty sentient. They understand about 50 words of Thai ( sadly about same as my Thai vocabulary), have a very considered approach to everyday problems, organize themselves into highly functional (mostly) non hierarchical groups. Are good at painting and crap at football ( like most beings outside Europe and South America they struggle with the offside rule).
You should try and meet one they are pretty good company.
