With the advent of satellite navigation in the late 1970s, and GPS for the US military a little later, there was a rush to embrace an electronic navy, so complete that the US naval acadamy at Annapolis stopped teaching real navigation where the navigator figures out where he is. It was considered obsolete. In 1998, Annapolis started teaching celestial navigation, and chart plotting again. The navy came to the conclusion that it was conceivable that GPS could be shut down.
We cannot even get air bags to work properly, so you can see the vulnerability of driverless cars. Its not that they will not be useful, its just that, like the Victorians with their steam and coal, we are intoxicated with our technological prowess. But what are we going to forget along the way: How to parallel-park? How to do long-division? How to write legibly? How to do anything during a power-cut? I cannot use my telephone if the power goes out. The US Navy recognises the potential for disaster from relying entirely on electronics and vastly complex micro-technologies.
Yeah - the US Air Force figured guns on fighters were obsolete, too, until they tangled with MiGs over Vietnam... now every US fighter has guns.
Stupid is as stupid does - WHEN the magic system breaks down how are these Navy boys going to navigate? By Braille? Oops - there's another rock.... back up ... oops.... a headland!.. damn.... try going sideways.... ummm.... buggar .... why is that harbour boat telling us to get out of Shanghai? Aren't we in San Diego? Tell 'em the US Navy backs down to nobody... oh.. he says there's a huge rock shelf ten feet in front of us.... ouch....
On the subject of everything automatic:-
They'd need to install cranes at every parking spot to get Fat Steve out of his vehicle for his daily intake of fifty Macca's products....
