As far as I can tell, "AI" is just a system for organizing and retrieving data that's already on the web.

That information is going to be only as good as information that's already on the internet. We all know there is a bunch of useless junk on the web in addition to the useful information. I think I'd like to know where that nutrition information came from before I put it to use. Different vendors and sources have different approaches to animal nutrition. 

And as Garvo points out, no AI bot is going to come look at your cattle with you and discuss what they need, what options are available and what are the cost/benefits for your herd.
