The only thing that’s set in stone is the past and that’s only because it has already happened. Predictions can be useful if applied alongside action (ex: “the weather prediction says it will rain on Thursday, so I will go the baseball game on Tuesday instead”). Without the action, they mean little. Things can reach a tipping point in one area or another, unforeseen crises can arise, and throughout it all, there are multiple factions vying for power, whether for selfish reasons, such as fascism, or humanitarian ones, such as anti-imperialism, decolonization, and liberation of the working class. Aid in the humanitarian struggle where you can; that’s where dire predictions are transformed into optimistic ones.
