You're definitely on the right track. Over here in Iowa, the dumb labor I've seen has almost exclusively moved to factories, with the full-automation tractors spacing out planting according to prior moisture and soil composition tests run over it by a prior-day tractor. Micro-farming is definitely a hot thing, too. The plants are now getting smaller, but producing huge yields. Food sustainability in someone's suburban backyard is almost here, though I do believe it's a bit more fiddly than the standard old-fashioned greenhouse-then-transfer for personal farming that we've seen for a long time. There's a business model waiting to happen for uninformed city-dwellers who want to get into the space, though it's more about selling education than a tangible product. But, if you're creative and savvy in the biology/botany/ecology space (I'm not), I've seen all sorts of neat configurations. One of the most interesting organic farming techniques I heard of was a guy who had a fish pond on one side, which cycled water to the other side that had a hydroponics setup, meaning it was essentially a micro-ecosystem.
