Indeed, takes a while for these things to unfold. For example, what we're seeing today is the result of the unfolding of the liberal program initiated centuries earlier. However, not only is taking time to unfold different from predictability, but specific predictions are not the same as general predictions. It isn't always impossible to make good general predictions. For example, some papal encyclicals have predicted with spot on accuracy the general character of how things will develop long before they did if certain things aren't sorted out. These sorts of predictions, in part, benefit from concerning the unfolding of philosophical (and theological) beliefs, beliefs which contains within themselves their own logical entailments. So these encyclicals weren't predicting particularities like "what will be the stock price of Amazon in 2030" or "who will win the presidency in 2030 and will this president like ham", but rather the general prevailing conditions, attitudes, etc. characterizing future generations and the resulting social order, for example.
