Ehhh really haven't. While you could argue farming is different due to it being more constricted, it really isn't and well unlike driving, this has a size constraint which has and likely will not be solved for in the near or distant future. It's complicated and might not be solvable. And well the current advancements while they seem nice aren't very useful. I know individuals who work in this sphere specifically and there are several problems alone with basic things such as sensors which are not adequate enough, if anyone attempts to solve this problem in the next decade I'd believe them to be the next theranos.
