If you where 29 would you become a farmer?
Robot manager might be the new job title, will an agronomist or farmer be more qualified for this.
I am not sure arable farming as we know it will exist in 50 yrs. It depends on who owns the new tech I am not sure farmers will, perhaps serfs is the new job title for tomorrows farmers.
If I was 29 ? Without doubt yes - very exciting times ahead for that generation
