We know that Nero's presence led to events being different from the Prime universe. We have no way of knowing if, for whatever scientific or dramatic reason they so choose, the writers will determine that the consequences of those changes will affect the past as well as the future
Are we talking about hypothetical future writers inheriting the franchise after the Abrams era? Because writer intent as it currently stands has already been examined and discarded. I don't think it's useful to gamble on the writers changing their minds. We should focus on the information we already have instead of relying on speculation that it might be thrown out.
Pauln6 said:, particularly where the past is dependent upon a future that will not now occur.
However, it is not. Generally speaking, that concept is backwards. The past is not dependent on the future; the future is dependent on the past. You continue to make invalid assumptions regarding the branching time travel. The presence of PrimeHead is not in any way dependent on anything that happens with the eventual Abramsverse equivalent of TNG. Whatever happens in the future of the Abramsverse is irrelevant. The presence of PrimeHead is guaranteed by the branching nature of the Abramsverse. It was a component of the past of the Prime timeline during a certain historical period. Thus it is in the Abramsverse during that period as well ( unless discovered earlier in the new timeline due to the butterfly effect ). Its existence cannot somehow be dependent on the Abramsverse future, which would be a logical cul-de-sac. It is not a result of things that happen in the Abramsverse future. It was already there in Nero's past and Spock Prime's past before the Abramsverse timeline was created.
Pauln6 said:We can debate temporal mechanics v writer intent but we just don't know.
This presumes that so-called "temporal mechanics" and writer intent are in conflict. However, fictional ST time travel, in particular that version resulting from previously unseen red matter black holes, need not adhere to the "realities" of theories proposed by scientists not involved in the production or consulting with the franchise. From an in-universe perspective, the claim that writer intent violates temporal mechanics makes little sense. It seems clear that writer intent would dictate that the time travel of the film works the way they say it does.
