How do farmers also have their fields plowed so straight for so far? Do they use GPS guidance somehow? And if they use some sort of tech, were they able to plow fields this straight back in the day?

As a farmer whose only equipment with GPS control is the sprayer, it’s all eyeballed.
Also, most decent farmers don’t “plow” their field every year. If you did/do, you’re destroying thr moisture of your soil year after year and bringing yourself closer to the dirty 30s.
Anyway, depending on size of the operation, fields can be either eyeballed or input into GPS. Older/smaller farms eyeball it. Newer/bigger farms use GPS.
If you really cared about being straight, most seeders/cultivators had marker arms, similar to how older sprayers had foaming nozzles. These would “paint” a line for you To follow so you could make sure you were maximizing your tool width.
Like the dodo, these have been phased out.
