There's certainly economically feasible models, such as sugar cane in Brazil or canola/etc oil crops and so on.
We've been competing with robots since 1974 (Score:1)
Most modern agricultural techniques are extremely energy intensive. We use fertilizer, pesticides, herbicides, mechanical planters and harvesters, and long distance transport, all which requires energy input. In 1940 the united states produced 2.3 calories of food for every calorie of fossil fuel used. In 1974, the ratio was 1:1 [harpers.org], and it's been getting worse ever since.
So we've been directly competing with robots for food ever since 1974. Our food supply depends upon a stable energy supply; this is n

If it's not economically competative and is supported entirely by subsidies, then it is either will have to get more efficient (do you really think the US will be able to afford all these subsidies the next time a major recession hits?) or it's just going to get optimised out of existance.
Stupid inefficient niches eventually go away.
Also, if there's more energy being pumped into farming, and the price of energy goes up, it can be reduced. We already see n
