Maybe, but where it’s hard for me to visualize something, I tend to disbelieve it. I think you’re just saying that because you can’t see a countervailing force on the horizon.

Apparently I'm not the only one who sees no solution. That's the entire reason it's a problem. On the one hand we have long-range problems like population divergence combined with an ossified set of institutions. That's a fact. The encroaching polarization and decline of norms is a fact.

On the other we have the absence of a solution.

I suppose you can somehow spin this into an argument that "something will come along"' but then, you can do that with anything.

History surprises us

And sometimes it doesn't. For example: we still haven't put an end to the nuclear age.I'm sure plenty of people imagined we'd come up with something miraculous sooner. Nor have we been proven wrong about what happens to nations like Japan when their fertility rate drops. And sometimes answers that were once denied because they didn't seem like they'd come true did (for example: the fathers of containment policy were eventually proven right, even though decades of science fiction set in the future with Soviets or socialist menaces had been written).

Ultimately, I don't see the point in this exercise. If you can make a good case for something being likely then that case should be made. If it is, by your own argument, unlikely then we live with the facts we have.

If the Son of Man comes on the clouds tomorrow and solves it in a way we didn't expect then we at least have the consolation of good praxis. But putting our faith in Him is a bad idea.
