Tractors have been “self driving” for over a decade, they just need constant monitoring because things frequently break or get jammed. And last I worked in ag the driver still had to perform turns at the end of rows, idk if that’s been improved since.

Which is to say that we’ve been (or had the resources to be) relatively post-scarcity for a long time, but to actually implement it would undermine the economic, racial, and patriarchal hierarchies that so many are addicted to.
