GPS and other satellite navigation systems can be replaced by a network of radio beacons. Its not irreplacible technology...
What does "replacing" have to do with anything? You said it was not useful in real world applications. It's quite useful.

... and its just 1 niche application.
Cellphones are niche applications?? What millennium are you in?

There are more than 4 billion cellphones in the world. That's better than 1 in 2.

10 year olds have cellphones. 10 year olds don't even have cars. Are cars a niche application?
