Right. We don't. And we never did. What I was saying is that when I was young, there was plenty of reason to believe everything would go to hell soon... and we were wrong, things got a lot better. There's just no way to know.

The last Romans living in the Roman Empire in 400AD may have also concluded that their problems would eventually be solved and they would continue thriving, just like they had for a thousand years. But they would be wrong. Just go back to 100AD and they would be mostly right: they still had a good 300 years in front of them (so they would never see a collapse, nor their children and grandchildren).

So yeah, eventually things will undoubtedly take a very negative turn. The question really is, will that be in 10, 100 or 1000 years? You don't know, I don't know. But given the above , I think it's fair to conclude that by being positive you're almost always correct.
