I don't want to sound totally econofuturoptimistic, but No, it's not de-skilling in my book. I'd venture robotisation is actually re-skilling or up-skilling. Or in other words: the average education level of the employees after more and more capital flows in, goes up. And automisation / robotisation is nothing new in agriculture. You need a lot less labour, that's true. But that's the trend in agriculture for about 150 years (as far as I understand rice is one of the few crops that's pretty constant in hours per bushel). Modern day large farms are run by a handful of people (and an enormous supply chain on both sides). An example: The Netherlands is a substantial exporter of food, and farming is about 1.5% of GDP. That's astonishing.
