There's no fundemental reason even a very fancy trsctor should need an Internet connection. Even with RTK GPS for ultra high precision positioning, you can operate a base station locally, and this is getting increasingly accessible. (You could do it as a hobbyist for about $400 worth of parts).

That's true as far as processing power goes, but software seems to be much harder (at least, more expensive) to maintain than the kind of machinery these tractors are built of. Maybe that's just because software isn't often built for repairability, or the kind of education that would be needed isn't as widespread.
