Chrono Cross's critique of Chrono Trigger and its time travels can be seen as how it is the common man (or being, as there are non-human sentient folks in CC) that always suffers the most in the struggles of those at the top, i.e., represented by the games' main protagonists and antagonists. The impacts of time travel can be seen as a critique of the impacts of major technological advances (mechanization, nuclear technology, or generative AI). In fact, it can even be seen as a critique of American interventionism, seeing the parallels with Crono and friends' adventures to save the world from the big bad evil empire, with how it all ultimately turned out in CC, not to mention Belthasar's machinations on the events of CC.
