According to Waver, magic has its own set of rules, so I'm not sure even that'd be a solid enough differentiating factor. I guess I tend to see technology as something more constructed, and so, more concrete. Like the parts I'm built with and why they work the way they do is all pretty grounded, seems to me.

At the same time, Waver's magic and Edward and Alphonse's alchemy both rely on exchanging something for the end product...
