I was telling my wife (who just finished OB for the first time this week) that if there is a spectrum between magical technology and engineering technology that shards, soulcasters, and other "surge" fabrials seem more magical whereas fabrials like spanreeds or heating fabrials seem more engineered. In addition to being much more recent developments too, the engineering ones have something to do with the spren. This connection led to the pun in the title for this new fabrial science.
Sprengineering
Hopefully this can become a field of study some day when there are universities and PhD programs on Roshar. And a fun word for the fan lexicon in the mean while
Also should I have a spoiler tag since the connection between spren an fabrials isn't explicit until OB? (or other pointers since this is basically my first post?)
