Start Timeline of the future in forecasts similar to Timeline of fictional future events. It should not be chronological, because we can't integrate forecasts from different authors. It should be probably split into several distinct fields, with entries in each field sorted according to complexity, closeness, not specific chronological estimates (still, it can be tried). However, each entry should be accompanies by different forecasted dates (by various authors). Only predictions and forecasts from acclaimed sources should be included, or at least that should be the goal. While the sequence of developments may be to some extent done by us, the predicted dates/periods should be taken from respected authors and organisations (it's not a problem if some of them conflict with each other).
Alternatively, make an article on famous predictions.
