Only a very small fraction of farmland produces food we directly eat. The OP's linked article has a great illustration of that.

We already produce far more food than we need. The amount of land in the US used for corn ethanol production alone is the size of a medium European country.

Data centers are not displacing food. That argument is disingenuous. Even in Italy agricultural land goes unused because of low demand.

that's the argument an AI will make to preserve itself.
