Have you seen the modern John Deere farming systems? It's likely going to go from the Interstellar intro to the plot of Ghost In the Shell 3. As in Fully automated farming; of that's vulnerable to getting hacked and becoming disease ridden.

I don't have against vegans, but I think it's important to have diversity since disasters have happened in the past. Like it or not, but animals are insurance against disasters that can happen to plants. Why do you think corn and soybeans have been modified so much?

There is no amount of watering plants in this current drought that will let me grow anything, everything I planted this year is dead. I have to adapt and create shaded and sealed greenhouse tents and then that's not covering potential flooding from rain as we've seen this year.

I'm just guessing, but I don't think it's too far away of having completely automated systems run farms. And I hate to say it but maybe it might be for the best in this situation seeing as I basically got sick from eating someone's shit on lettuce.
