HA! Try growing or raising animals and not using Amazon...
(Depending on how abstracted you want to get, but yes the farmer probably filled up their pickup for the morning delivery at a gas station that has a POS that connects to some service that interacts with AWS somewhere a long the line. Though the farmers I’d met likely used cash)
(If you're suggesting that farmers and ranchers should go back to the days before production of plastics, hard goods, petroleum products, and rubber materials...well then they will cease to be farmers or ranchers, because 1700s-era tech won't survive market forces today.)
Similarly, no one can build computers in the US any more. Apple's Mac Pro project is interesting, but very low volume and mostly just an assembly effort.
I would counter that "old" farmers were able to use the seed from the current crop to plant for the next season so that it was self-sustaining. Now, with modified seeds from places like Monsanto where the plant from the seeds of this year's crop will not produce fruit. This forces you to need to buy new seeds each year.
I'm also suggesting that we go back to planting more than one crop per farm, and then even switching which part of the farm each plant is grown in. Crop rotation is such a huge concept that we've just thrown away. We can still use "plastic" and even "smart" equipment. We don't have to go back to stone age tools, that's just daft. We had that before July 5 1994 too.
I'm glad for the research I did 15 years ago; I still encounter situations where it becomes relevant, e.g. this discussion here and why certain water pipes are colored purple [or other colors, but at this time I remember only what purple means].
But supply chains for agriculture are a lot more complicated than sourcing seeds.
I agree with you that the current state is unsustainable. On a more general level, again, it's similar in manufacturing. Seeds or other raw materials, tractors or other specialized equipment.
Globalization adds and subtracts different kinds of resilience. Specialization only subtracts resilience.
Neither of our points has much to do with AWS though. :)
I'll buy elsewhere if it's < 5% more. I've no problem paying £5 delivery on a £100 item just to support 'the little guy' all other things being equal. But on a £10 thing, Amazon wins.
(not a farmer, but the point still counts)
