Manned submarines are the past
A perceptive summary by John of the collective delusional propaganda cocoon in which we in Australia and the West more generally continue to live. That cocoon comforts us with the reassuring belief that a technology that is already four hundred years old (submarines) will ensure our dominance into a future of vast and largely unknowable technological change.
With the advent of inexpensive unmanned underwater submersibles and the vast leaps being made in underwater detection of increasingly huge manned submarines, by the time we get these subs, assuming we ever do, they will be the aircraft carriers of today. Increasingly visible from space and vulnerable targets for inexpensive drones and hyper sonic missiles. By the time they arrive, if they ever do, they will represent vastly expensive and radio-active fish reefs!!
