Incorrect. I worked for an Ag tech company for almost a decade. Ten years ago, farmers were downloading high resolution satellite imagery of their fields directly to their GPS enabled precision sprayers so that the spray rate would adjust continuously based on the vegetative index of the land they were over. I don't know what state of the art is today, but I imagine it would surprise folks who aren't in the field.

Vision systems for weeding are effective. Instead of spraying everything, cameras look down as the sprayer is pulled behind a tractor, and only weeds get sprayed, or zapped, or hammered. Uses far less pesticide. Deere and others sell this. Deere prefers to sell this as a service, where farmers pay fees when the vision system is enabled.[1] There are a bunch of autonomous robot startups with similar systems, but none seem to have grown much.
Tomato picking robots have been demoed since at least 2018, but still aren't used much. There are at least half a dozen startups. It's not hard to do with off the shelf robots, but not cost-effective yet.
Automated cow milking is used in New Zealand and Australia. Those countries have extensive agriculture but not much of an underclass, so they have to pay workers real money.[2]
Automated meat cutting is also used in those countries.[3] Mostly lamb, which isn't a big thing in the US. Fully automated beef lines don't seem to be available yet, although the company that builds the lamb systems is getting there.
Vision-based sorting is automated, fast, and cheap.[4] That's why when you buy packed berries, there are no bad ones any more.
All the big field crops - corn, wheat, hay, soybeans, cotton - were mechanized decades ago, of course.
What else is actually working?
