I am thinking that I know why my planet seems so alien and strange to me now I am getting closer to my 70's. And that would apply to everyone – all generations.
“Old” people always complain that the world is “worse” than it used to be. But, believe me, in a lot of ways – it IS! For generations, old people have been known for feeling that. Sometimes, maybe, things are better, but they can't see it – but they can feel a “difference”. And that is true. The planet is actually NOT the same a it used to be when old people were young.
And the reason is this. Every 72 years the planet precesses one degree in its precessional cycle.
So, in the cosmic rhythm of precession the planet is literally not the same as it was when we were born.
