To my understanding, the tech-as-magic or real-magic line is deliberately fuzzy to allow GMs to adjust to their own tastes. It is very easy to run Pugmire as straight medieval fantasy with very little allusion to the leftover human tech, it would also not be hard to say that all magic is actually just Sufficiently Advanced Technology if you wanted to play it that way. My game was probably about 80% magic-is-magic with the super-advanced-tech-as-magic thing only coming in a few times.

In both cases the Unseen are a real threat to dogs and cats both....
