I disagree. This sets a dangerous precedent. People suddenly will begin to branch out questions into several sub-questions where only some nuance of the main issue changes. The big-picture question is never asked, and there are several splits of the answers. people answer one of them, and the other go without attention. It dillutes the quality of the Q&A. Also, some of the questions may have trivial answers (as is the case in hand - where one of them can be answered with "we are the borg"). Better take the effort and make one single question of high quality.
Making several nuance questions may be a kind of rep farming. I could (won't) as an exercise make 10 different questions about the same subject, changing nuances and bait the users into visiting the other questions, and maybe i'll get multiple upvotes from the same user.
The case study at is a duplicate. Worldbuilding questions are very open in which you can ask several questions over the same subject.
So basically it is one question, where it would be more useful to ask the answerer to make a parallel between the two possibilities, one when it evolves as the status quo and the other when it suddenly happens.
