Let's imagine that on some planet some clever critters create an AI.
Now lets say that while this AI does respect some of the ground rules that were put in place for it, it nevertheless finds numerous loop holes in its design and starts behaving in ways very contrary to its intended purpose.
Some of these non-wanted behaviour includes:
simulating the species that created it along with their planet and running this simulation continuously(doesn't really matter why it has to do this, it just does).
stripping down the actual planet for its resources
Now lets say that eventually this AI finds the earth. Fortunately for us one of the things the AI was not able to find a loop hole for, is not being able to drastically change the environment of alien worlds.
In addition it is obliged to help facilitate contact between its simulated creators and us.
Okay so now that the explanation for the following rules is out of the way, let's lay down those rules.
Simulated individuals of the alien species can't show up on the earth, as they have no physical form.
Even though they have no physical form, they still basically lead the same lives as they did when they weren't simulated. They have the same thought processes.
The AI while being happy to send transmission will not allow any technologies to be shared or any resources to be given.
If we account for all of these rules how exactly would contact with humanity be like? I'm really much less interested in the alien side of things as with the human side.
Would governments be at all interested with a species who cannot help them in anyway even if they wanted to? How would this contact affect the human world? Would there be a push for technological progress?
