I came across a video clip showing how farming is automated in China. It’s not widely adopted yet, but I don’t think the day when that happens is too far away from now.
This is how farming is done in Vietnam

Admittedly, even though there must be innovation in agriculture in Vietnam and technology is used to some extent, the photo above illustrates the current inferior technique adopted in my hometown.
Imagine the difference in efficiency and value created between the automated method and the manual laborious one.
If you are one of the workers who don’t own land and who is hired to work others’ land, automation isn’t good news for you. Your job is threatened. Nonetheless, if you are in the agriculture business, automation is a boon improving efficiency and lowering costs. If you are an end user consuming agricultural goods, automation can bring the prices down.
If we look at it from a collective standpoint, technology or automation in particular, in the majority of cases, should bring net benefits to the society. Innovation and advancements come from standards continuously being raised, I believe.
