I did some work in the early 2010s that we expected to be used for computational photography, gaming, and little else. Years later, after I had already left the company, its primary use case became image stabilization for quadcopter drones, something that had not crossed our minds at all when we were building that stuff.

Cue in all the drone footage from the Russian invasion of Ukraine. FUCK. FUCK FUCK.
