"You don't got to frame walls anymore!", something that is the most enjoyable part of residential construction, takes like a day of work at most, and can be done while on autopilot. "We can instantly generate wall plans for stud location from top-down blueprints!", oh that thing people do in their head because they just space it all on 16 or 24 inch centers and it doesn't actually matter which side you start on? "We can wirelessly drive your tractors!", the easiest task on the farm which all the weeks of maintenance and planning and setup led up to?
Now don't get me wrong, there are many things that can be improved in those industries certainly, but you aren't going to know what those things are until you actually go on the job site and learn how they currently do it daily. Most all of the low hanging fruits have already been picked one way or another and a fancy step stool is not going to be industry changing.
