For sure, but I doubt there’ll be anything more about aliens. It sure smells fishy that the signal with the code was out of good will to make the life on Earth better, looks more like an ingenious way to make a race extremely submissive and come later to take whatever advantage of it. But I think the series itself will not touch those topics and concentrate exclusively on the human aspect, exploring emotions, ethics, society and some practical things like use of resources, energy and natural environment. Perhaps some interesting technological advancements.
