I have a theory that Kirk Prime is actually alive and well. How to explain it kind of depends on how one feels about time travel rules in Star Trek.
I'm a bit unclear as to whether this discussion belongs here or in the Kelvin thread but it kind of has elements of both so I'll leave it to the moderators.
For decades, Star Trek had a very simple view on time travel--if you travel back in time and do something, you can change history. Some of Trek's finest stories have been based on that principle, from City on the Edge, to Yesterday's Enterprise to First Contact and many more. Pretty much every time travel story we had involved the risk of changing history.
There are always some loopholes, often to make the story work, that the time traveler himself is immune to the changes in time travel. If not for that, Kirk and crew disappear when McCoy saves Edith, and there is no Enterprise D to stop the Borg.
If you solely go by what you see on screen, and I am in that camp, then when Spock and Nero traveled back in time, they erased all the stories we saw before that movie and the Kelvin Timeline replaces the Roddenberry timeline completely. Spock Prime and Nero still exist, because again, the time traveler somehow is immune to these things.
This is been a debate between Star Trek fans for a long time, because JJ Abrams, off camera, tried to use his own time travel rules. He explains that when you travel in time, you create a new universe, and the timeline you left still exists. That's perfectly acceptable, except that contradicts everything we know about time travel rules in Star Trek, and would take away the risk and reward of all the great time travel stories we saw.
Worse, given that canon is what we see on screen, Abrams, who had the right to WRITE those lines in the story, chose not to. An alternate reality, as Uhura calls it, happens in all cases of time travel, but that does not mean that the original reality still exists.
Because of that, I've never been able to accept Abrams' statement since had he wanted that, he could have put it in the movie and made it crystal clear.
Of course, other universes DO exist in Star Trek, as we saw in Parallels and Mirror Mirror, and they have also been a part of some of the best Trek stories. However, nothing in ST09 mentioned that Spock Prime was from an alternate universe. Every time that universal changes happened, it was crystal clear that we were being treated to that story. If time travel happens, the timeline is at risk. Not so with changing universes.
So while a universe identical to the prime universe exists, it's not THE prime universe because the timeline changed. I do think that if they ever wanted to do so, they could override this presumption with dialogue and a story, but so far, they have not done so.
All of the above is more of a Kelvin timeline topic, and this is more about Generations.
I would argue that under both theories of time travel, Kirk Prime is still alive. I'll save the Abrams version of time travel for later, but it seems pretty clear that the way the nexus was set up, you can exit at any time, in any place, but you can't leave in a place where you already exist. If you do so, your other self will cease to exist, replaced by the version exiting the nexus. Guinan's echo said she couldn't leave because she was already there. Based on the fact that Picard's pre-nexus self was not there, it would be easy to argue that had Guinan left with Picard, she would have wiped out 78 years of her life, including everything we saw on TNG, and that's a lot to ask, when Kirk was in the nexus.
Picard only lost about 10 minutes and a beating, so it wasn't that big of a deal. Also, since Kirk didn't exist at a point after he went into the nexus, there was no Kirk to replace, which is why Kirk could exit there.
Had Kirk exited on the Enterprise B or before, he would have replaced himself.
I believe that when you're in the nexus, a version of you exists in the nexus at all times and places, capable of exiting--until the nexus itself is destroyed. If you can exit at any time, then if you enter at any time, you will have access to anyone who ever went in the nexus, and they would be capable of leaving. Essentially, an infinite number of Kirks and Picards.
So that's one way Kirk survives.
Another is much more simple. Under Roddenberry rules, Picard and Kirk traveled to a point in the past, even a short point, before Picard entered the nexus. In the nexus, Kirk was chopping wood while his future self was helping Picard ready to get killed. By stopping Soran though, Picard never enters the nexus, and that version of Kirk then never leaves. His doppleganger is dead on Veridian III, but Kirk Prime is still in there because Soran never destroyed the star and Picard never encountered Kirk Prime.
