Yes, humans are doomed, but not by overpopulation, not by oil, running out and not from the sun going red giant.
We are right now currently growing enough food to support 12 billion people, and with a population of just over six billion, that gives us plenty of growing room. It wouldn't take that much for us to increase our food production either. Space isn't a problem either, we can still build up and down for living space, i.e. buildings.
When natural oil runs out there are still plenty of other fuel possibilities, such as fuel cells, alcohol(made from corn which we have plenty of and is renewable), and for electrical generation there is nuclear, wind, and hydroelectric.
It's going to be roughly another four billion years until the sun goes red giant, statistically by then we will have had 40000 large meteor impacts, not all on the scale of the one that killed the dinosaurs, but large enough that they will cause climate changes,i.e. ice ages. So I think that we'll be wiped out by at least one of these well before the sun kills us, if we haven't left the planet yet.
And if we haven't been able to advance from this stage of technology to something along the lines of Star Trek in FOUR BILLION YEARS, then we don't deserve to live.
If Nuclear War breaks out I bet it will be because some President in the future decides that since we are the most powerful nation(militarily) and we have the best form of government(Yeah, right) then we should unite the world under the rightously free oppresion of the United States. And since the other countries are gonna look down on this idea, we're gonna do our best to wipe each other off the face of the planet with nukes.
