The Holy Grail

[timelets]

upd: Something is missing from this OLOG. First, at least "a solved problem" should be mapped to ex post. In general, everything should be mapped to ex post and ex ante or a timeline. Feasibility and value judgments should be mapped to a range of values. Second, intuitively, the best combination should be (an unsolvable problem & a problem worth solving), but the diagram doesn't show it. Maybe I need to introduce "solvable - unsolvable", similar to value and technology judgements.
