To attempt to predict anything beyond the relevant horizon is futile – it is prophecy – but wondering what is beyond it is not. When wondering leads to conjecture, that constitutes speculation, which is not irrational either. In fact it is vital. Every one of those deeply unforeseeable new ideas that make the future unpredictable will begin as a speculation. And every speculation begins with a problem: problems in regard to the future can reach beyond the horizon of prediction too – and problems have solutions.
