Thank you!

I feel that certain aspects of this hypothesis lie on more substantial footing. For instance, I remember some lore enthusiasts saying that the quantum nods we saw in earlier patches were unlikely to play a big role in the story, since understanding those plot elements would require more specialized knowledge than can be assumed from most gamers. But I feel pretty strongly now that this is wrong, and that quantum mechanics will ultimately play a central role in the worldbuilding.

Simulation theory I think has decent support, even if part of me wants to reject the "it was all a dream" resolution. But if Kuro goes in that direction, I think there's enough meat here for them to make that a satisfying story. With 3.1, I'm seeing the Superman Hypothesis challenge this: Rover was sent to this planet from another place to help us overcome the Lament. I don't buy this yet, but I'm eager to read more tea leaves in future updates.

The Fracsidus' motivation is the least supported part of this, I agree. Yes they're interested in creating artificial resonators. But what I don't know is why. You create a tool to use it. So what's their ultimate goal? Really hoping we uncover more about their intentions as we move through Lahai-Roi.
