Ask HN: What unusual areas would benefit from automation?

Fruit picking, it has already started but could really take off.

Also, talking to a guy at work whose in-laws own a super popular Chinese restaurant where I live, manufacture of some dumplings. But this one is super hard when you look at how long it takes a person to learn to do it just right, mostly by feel, as all flour is different and changes day to day with humidity.

I don't know if it counts as unusual, but I want a robotic gardener that identifies weeds and zaps them with a laser (or otherwise kills them).

...and it seems like there could be quite a sizable market for such a device that automatically helps grow your food.
