Like much technology its still in the wrong hands.
I'm not saying I'm the right hands but I have a Pi3/Camera combination that currently recognises the difference between a chicken, a duck, a rat and a Magpie with over 90% accuracy. This is quite useful when it comes to stopping the latter two nicking the food and eggs. If I can get it to 99.9% on the rat I might just automate a trap and for the magpie a loud alarm (which would put the hens off lay). Its not much but it would pat for itself quite quickly.
A similarly trained device for insect recognition (with a laser!!!) could roam crops and do away with need for pesticides, and indeed weed recognition could also reduce the need for herbicides. Both solutions in mass production could work out cheaper than the chemicals without the likelyhood of resistant mutations cropping up (OK you do get mirrored beetles and silvered plants).
Useful solutions will continue to develop - its twats trying to sell you shit you dont want that are going to have a winter not AI.
