For example, in my neck of the woods there’s the company Carbon Robotics, which is pretty successful. They develop autonomous tractors and a laser weeding system both of which have good adoption and sales at megafarms. They decrease the cost of herbicide application and labor significantly. That’s just one such company. It’s to the point that farms go fallow, or convert to solar, because the revenue produced farming isn’t enough to justify farming because we would be feeding people for free otherwise. That, my friend, is artificial scarcity. So keep toiling for your food coupons and convince yourself that the market is infallible.
If it's so easy this is ripe for a startup to disrupt. Food is the most necessary thing to human existence. Every living person is a potential customer.
But nobody is saying "people shouldn't eat for free, therefore I won't grow crops."
You said it yourself: farms are left fallow because the revenue doesn't justify the cost for the farmer. That, my friend, is basic economics, not artificial scarcity.
Who is this "we?"
There's a kind of circular complaint built into all such endeavors that goes like, "we can do this, but unfortunately we as a group don't want to, but we could definitely do it if we wanted, but sadly we currently have the wrong opinions, but we can definitely do it, if only we weren't inclined not to, but we should and we will, as soon as we all come around to the truth."
Your "we" doesn't seem to want to do what you want them to do, which is why communists so often end up thinking that the real problem is the existing populace and maybe what they really need is to be re-educated or even replaced.
As opposed to other technologies; microchips do not grow on trees.
