I think that the premise of Terminator could be humorously framed as 'Man fights Progress'.
That's going to sound bad off the top for most ppl, but I would ask 'Does it sound bad bc it is bad or bc you have a preconceived notion about progress being good?'
In the film, 2 men are hatched out of giant time eggs, naked and destined for each other bc they both want the same girl. (lol) The difference between them? One is a normal, vulnerable human fighting against the odds. The other is an unfeeling, uncaring machine concerned with consistency and fulfilling its mission. How long can man persist vs the machine? Can we go back and change things?
So, you see, Kyle Reese and all future protagonists are from a future where humanity has been split into two tribes- Machine and human. New vs old. Technology vs the old ways. So in an almost literal sense, they are fighters from the future fighting in the past to change their present. Is man obsolete? (T1) Even with the tools of the machine? (T2).
So, assuming the machine represents, among other things, progress, that makes ppl recoil bc that's a word with a positive connotation, but I would hesitate to say it's always positive. The Amish have based their life on the idea of fighting progress and it seems to work out for most of them.
In order to know if the progress is good or bad, we have to understand what we're progressing towards. Saying 'at least we're making progress' is like saying 'we're changing', but into what? If a company is making progress towards bankruptcy or a class action lawsuit, that's not good progress. If a missile it making progress towards its target that might be good progress for whoever fired the missile and no-so-good for whoever is in the target area.
So when Kyle Reese fights the Terminator, he is fighting progress, but he's doing it for the good of mankind bc at some point it's possible to progress so far we make ourselves obsolete. We create automated systems that are far better than we are at doing our jobs.
But without our roles, what identity do we have? And if all we're going to do is hand everything over to machines and allow them to babysit us, take care of us like we're inmates in a prison or animals in a zoo, then what is the point of society in the first place? Life, Liberty and the Pursuit of Happiness? The betterment of mankind?
I think at some point, we need to take serious stock of the direction we're traveling in and decide if progress towards that end is something we all want to see.
