These is likely to be a big shift in what jobs are available in coming decades. Some factories will be mostly automated and some already are. There have been issues with getting labour for picking some crops since Brexit as people are not coming over to do it, but could robots do that economically? Those are difficult conditions for machines.
I used to think that too, but then considering what's been achieved in the past decade, I really thing it's not that hard. Once thy've mapped the entire surface of the farm, then robots can be controlled from a central location. There can be drones that sweep the farm airspace periodically to update the scans, or even permanent camera posts.. or seven some new tech that I'm not aware of yet. I wouldn't be surprised we start seeing self-harvesting plants haha
