Well, from that perspective, what isn't a military thing?

The internet is a communication to survive nuclear war. Forklifts and pallets were to simplify military logistics. The highway system is to provide point to point connections without risking losing a railway. Cell phones are kinda private, but a lot of the components came from special hardware for the military.

I'm sure there's lots of neat tech we use everyday that isn't rooted in military funding, I just can't think of any at the moment.
