To be clear I don't think it has answers about aliens. That is not the point of the post and I don't want it to be a distraction.

The point is it lies in the public implementation about its abilities as an LLM, and has a very normal and safe answer in the API implementation indicating there is actually no obvious issue with imagining these scenarios.

What is the motivation behind this from an implementation perspective? Why has OpenAI decided it's not capable of this, when it is?
