I absolutely love the different themes people are taking away from this, it makes me so happy. Admittedly, I wanted the main question to be ambiguous so that more focus is on the computer's reaction to it (and its lack of restrictions/parameters). So really, that's however you'd like to interpret it! But if you want an actual answer: the computer was installed in a research facility and they asked it that question, hoping that it would say "combine these medicines" and then that would be that. That's the author's headcanon. Not necessarily canon, because again I'm liking all the interpretations people are coming up with and don't want to step on any of them. But certainly a headcanon.
Thanks for the detailed review!
