The author makes some interesting observations that people not living in dense cities may have noticed. I think the prediction of autonomous low-speed cargo bikes is a bit far fetched and will be chronically "ten years away", but it does highlight the complexity of logistics, for which global companies like FedEx and UPS have to adapt to in the changing urban environment.
As for standard cargo sizes, the author is very careful with his words, predicting that RORO boxes will be standardized, not that all cargo bikes will adopt this shape and form. That's an important distinction, since national and international shipping rely on fitting things together, like Lego bricks. But consumers? They vote with their feet.
Indeed, you can get cargo bikes and trikes in all shapes and forms, and none so far have won out as the dominant form. Whereas standards that the world has basically adopted through sheer use include: the TEU shipping container; the approximate 4-5 ft wheel gauge for automobile, wagons, and chariots going back to the Roman era; standard gauge rail (1435 mm); the SI units (which the US foot is based on, post 1959); bicycle and motorbike chains on the starboard side.
If international shipping settles upon a pallet or RORO box size for their use, then that'll be entirely separate from what consumers will be riding. Not less your hobby involves buying pallet-sized quantities of goods and hauling them back yourself from the shipping terminal.
