The challenges of this new concept are many: Simplicity, repairability , spare parts, cost, complex software.

I understant a desire for modular versatile vehicles, but why would someone Buy a single chassis and spend a lot on specialized modules which have occasional use, when there would only be one or perhaps two active vehicles working and a bunch of specialized parts left in the barn? Would it not be more efficient to rent specialized vehicles when needed from a central supplier? And it I was a central supplier would it not be better to have vehicles to rent rather than add on modules?

The very complex display shown in the video implies a very highly skilled operator.

If there is a shortage of workers, would it not be worse to have to find highly skilled operators? Even with driverless vehicles I wonder if there would be a skill shortage.

Would not a purpose built specialized machine not be more efficient than a complex modular one. If the terrain flat and controlled, I see limits to the need for highly adapable vehicles.

There appear to be many comples electronmechincial and hydraulic systems in each vehicle, needing specialized parts- how can field repairs be done efficiently? Isn"t there more to break?

How would field repairs be accomplished? By dealer mechanics? Or, hypothetically robots (where, when, how much money)

How would this compete in the third world where more and more agriculture is still needed and labour is cheap, but slowly becoming less abundant and affodable? China producesmany extremely simple and inexpensive machines .

There are enthusiasts who are considering open-source plans for machines, maybe this is the key to progress with new concepts. See global village construction set.

All things to think about when planning the next generation of machinery.
