Couple that with the imminent arrival of driver-less cars that, they say, would be near impossible to crash and you have a world that hardly resembles the one we now live in.
Those examples aside another sea-change caught my eye last week, albeit one of less magnitude than supersonic flights to London.
A Sydney state secondary school is now allowing boys to wear skirts to school and to use the girls' toilets if they so desire.
They can refer to themselves as being of either gender and likewise girls can attend school in a boys' uniform.
Simply because I don't want to have to field howls of protest I am going to refrain from commenting further, or from passing any sort of judgment on the school's decision.
All I will allow myself to do is stick to the undeniable fact that it is a far cry from my own schooldays.
I could not imagine myself, or any other boy in school for that matter, arriving in a skirt at Greytown Primary School or Kuranui College unless it was a prank or perhaps to fulfil a role in a school play.
As for attempting to use the girls' toilets, well you can scream sexist if you like but that little escapade would probably have seen a boy chastised the first time - or caned - and expelled thereafter.
