We'll always be able to say "But what if things get worse again?!" just as we'll always be able to say "What if things carry on getting better?". Any answer to the question is useless. We should guard against doing things to make the world worse, obviously, but I don't see much value in pessimism, especially if it requires ignoring a long term trend.
That said, speculation about the future beyond a few years away is largely pointless anyway. We get things wrong far more that we get things right, and when we are right it's mostly because we were either lucky, we've only looked at the predictions we want to look at and ignored the wrong ones, or we were so vague we couldn't have been wrong. Predicting the future is hard.
