Well, in true saber metrics form, I'm not saying it WILL happen, but I think it is highly likely, and we should be planning for such an eventuality. And, we are supposedly less than 5-7 years from trucks self driving, so I'm not sure why farming won't be similar. heck, I'll give you the farmers.......if you give me the miners, many of the firefighters, much of the military, a huge swath of lawyers and accountants, IT people, call center people, what is left of people inside banks, under writers, much of the teachers......taxi drivers, waitstaff (ipads are already starting to take their place) at less expensive places, on and on and on. I think a lot of people will want to work, I think there won't be as much work.
