A very common thought in speculative Design. Eben if it is a bit true event in the future, an imagined event can change the present as the perception of the past. See utopias and dystopia as example. If we say this known known in the future it already affected the present and also the past. It gets interesting for the unknowns unknowns if those will change the past and present. But already accepting that there unknown unknowns changes the present.
