Ha ha it's definitely presented tongue in cheek, but that doesn't mean it's not wholesome, (how can it not be?) Or desired. Seriously, those 2 are like majorly overdue some good karma.
You should DEFINITELY stay away from theories with Xenoblade.... And what you said makes me think I should really make sure to remember to also spoiler serious speculation.
Xenoblade, has a surprisingly solid vision with very solid narrative rules based on real-world sources, historical (religious symbology, the uh, dead philosopher society, computer programming), and fictional (the Space Odyssey franchise, Takahashi is a Gaga head over heels megafan, of both the movies, of which he has recreated quite a few scenes from across the xeno games, and the books, most people are only familiar with 2001, but there are 2010, and 2061 which is where he pulls stuff like the wave form existance (former astronaut Dave Bowman), upper domain and whatnot from). Which makes it seemingly pretty easy (and satisfying) to land squarely in the ballpark of nailing the underpinning framework of what's going on.
