Yeah, once again, if the Khan miniseries Meyer is doing is covering the Eugenics Wars, there is approximately a 0.00001% chance that it will take place during the 1990s.
I dunno about that. After all...
Khan also said 1996 in TWOK.
...there is this. And...
Yep. And at that point, there was still some fluidity to the time frame Star Trek took place in. Early-23rd century and late-20th century could be rounded to be 200 years apart.
...this, too. Khan also bragged to Terrell that his people were "sworn to live and die at my command 200 years before you were born." And Chekov described him as "a product of late twentieth century genetic engineering."
Surely no one thinks Meyer or anyone else making that film in 1982 imagined such things were going on at the time, or that it was likely (or even possible) that the Eugenics Wars would take place just ten years down the line? They were treating Trek's history as a thing unto itself, separate from our own.
I agree. I've always felt that Star Trek was in our future. That's what made it inspiring to me. So keeping future history in the future is a conceit I'm willing to accept
Whereas I have never felt that (mainly because that it's wildly at odds with loads of evidence both from the show and from the real world). Yet that distinction has never diminished the show for me in any way. Like much other SF, its aspirational ideals (and warning parables) are no less potent because they're set in "unreal" histories.
Or the writer didn't know what year the movie took place.
Nobody knew what year the movie took place. Trek didn't pin itself to any specific Gregorian calendar years until after TNG's "Neutral Zone" in 1988 specified the year as 2364. Prior to that, the best (unofficial) estimates put TOS in the first decade of the 23rd century (per, e.g., the Goldberg
Spaceflight Chronology).
It will confuse newcomers and casual fans way, way too much, IMHO. Though it would be easier from the standpoint of prop design, and much more interesting stylistically.
DSC certainly doesn't seem to have avoided
anything on the basis that it might confuse newcomers and casual fans. (Dunno about you, but I have personal testimony to that effect from more than one person.) Granted DSC doesn't seem to have a clue who its intended audience actually is, still, that at least means we can't generalize from it about future projects.
One thing I do wonder about is how for a person who denotes canonicity based on continuity deals with other oficially non-canon products being in-continuity with oficially canon products. For example any given TOS novel from the last couple of years... That's also why declaring canon based on continuity always feels a bit like meshing together head-canon and canon.
I think that's what most of us do around here, actually. At least I certainly do. "Canon" merely denotes that something was onscreen; that doesn't say anything about the quality or consistency of its story. My personal sense of Trek
continuity is based very much on my headcanon, and includes a lot of licensed material, and a lot of unofficial rationalizations of contradictions freely floating around in "canon."
