Coming to farms: AI robot weed killers

A new generation of robotic weed killers could disrupt the $100 billion seed and pesticide industry, reports MIT Tech Review.

The method would eliminate the need to blanket entire fields with herbicide, which could pose a threat to business as usual for giant chemical companies
