Outside of the large corporate farms I think you are going to see an increase in farmers continuing to refurbish older tractors that are pre computers and then begin to retrofit those tractors with third party systems that won’t give them complete vendor lock in. A good example is Welker Farms. They run Big Bud tractors from the 70s refurbish them every decade or so. And have added in gps guidance and other things as 3rd party mods. Also they have a great YouTube channel[1].
That's the thing. This big iron equipment doesn't just quit working and fall apart after a few years. It's expensive enough that you rebuild engines, weld up parts that break, redo seals in the transmission, etc, and keep it going for decades.
I've driven Cat D6 bulldozers that were older than I was when I was in college, and they are still going, a decade later.
Particularly the stuff that is built for heavy usage has to be used hard, patched together with limited repair facilities in remote places, and handled by inexpert operators.
