ABSTRACT
In connection with forecasts for the future, the following phrase may often be heard: forecasting is a thankless occupation. It is meant by this perhaps that life and reality are much richer than our imagination and forecasts often prove to be erroneous. More important is the circumstance that unpredicted and unexpected discoveries are the most interesting. They cannot, of course, be prognosed and, thus, the validity of prognoses seems to be particularly questionable. Nevertheless, attempts to foresee the future seem to be reasonable if one does not attach too much importance to them. This is what I shall do in concluding the present article by a forecast concerning only the problems mentioned earlier (I apologize for some repetition).
