Are you saying that has failed? It isn't obvious to me from that page that anything in particular is going wrong. I don't think anyone is daft enough to claim that AI solves the "Iowa remains unplantable due to winter conditions" problem.
logs suggest it's been 'critically failing' and 'blocked for 68 days' on farmhand introduction, although the logs don't go back far enough (and cut off too early) to really tell what's going on. https://proofofcorn.com/log
Looking at the timeline they seem hopelessly behind. Its currently the planting window and they don't have land or a person to work it.
