hmm... having grown up on a farm in Germany and even though my father was only employed as the manager, it still felt more like "our" farm. It was definately a big farm compared to the german average, but then that average also includes a lot of part-time/side-business farms, where.
Despite the size, the general methods between a smaller and a larger farm are not that different imho. But the amount of tech in a modern tractor was and still is amazing, and at the time the average car was definately not up to par. "automatic" GPS assisted driving, "laser" assisted driving (on harvesters). Beyond that, most of the "management" data was already digital 15 years ago, partly due to compliance requirements. And satellite imagery, soil samples, etc... were at least partly integrated.
And I would still call this a farm! Times change, and clinging to the old times in some nostalgia doesn't help. (I don't want to imply that you do!)
And on a slightly different perspective: I don't think bigger farms necessarily produce worse food, generate more externalities, etc... The processes are much more optimized, and at least I think the potential for better food with less externalities is with bigger farms. Also it is a somewhat bogus comparison: Mostly nobody complains that their car / laptop / smartphone comes from a factory, but for farming there is this strange preference for something of 50-100years past.
