Combines may have made it possible to increase an individual farmer's output, but at what cost? Haven't we all experienced the replacement of the quality, handcrafted item with the cheap plastic mass produced part planned to break in x years (or months)? Sure that's acceptable for some things, but with our food?
Food security is enabling, empowering. And if you're considering it back-breaking, or doing so much of the same task as to need machines, or to consider the work boring, you're doing it wrong. We have a 1 acre, highly diversified, mostly perennial farm, aiming at low-input sustainability. If you don't bother with annuals, that saves you a ton of time. Having the diversification means you don't have accumulations of super-pests, and hence less need for costly poisons. If you plant enough nitrogen fixers, and have enough animals around, there's no need for fertilizer. If you treat your farm less like a crop, and more like an ecosystem food web, there's a lot less work to be done. You introduce new species, you let one element feed the other, you let them multiply for themselves, and you harvest the surplus. Anything else is fighting nature, and hence, introduces work.
Having food security then enables one to be free from the whims of the food, oil, and job market. I would think anyone, including the software programmers (such as myself), would want such security, at relatively low input, and one that involves enjoyable, diversified work. It reduces risk and unties your hands, to take those professional risks you might otherwise wish you could.
