This is Bloomberg Opinion Today, an updated Bayeux Tapestry of Bloomberg Opinion's opinions. Apple Inc. recently added audiobook narration to the growing list of occupations where algorithms are poised to replace humans alongside graphic designers, college essayists and limerick writers. Luckily, the fine art of newslettering remains (ahem) far beyond the capabilities of even the most sophisticated artificial intelligence software. Still, hope is at hand for those not fortunate enough to toil in the newsletter mines but still seeking gainful employment that won't disappear as robots take control.

News that Alphabet Inc.'s Google sidelined an engineer who claimed its artificial intelligence system had become sentient after he'd had several months of conversations with it prompted plenty of skepticism from AI scientists. Many have said, via postings on Twitter, that senior software engineer Blake Lemoine projected his own humanity onto Google's chatbot generator LaMDA. Whether they're right, or Lemoine is right, is a matter for debate -- which should be allowed to continue without Alphabet stepping in to decide the matter.

A robot army is beginning its march across rural America, promising to transform the future of food. Twenty-five intelligent machines were dispatched last month to the Midwest and the Mississippi Delta, where they will advance over newly planted fields at 12 miles an hour, annihilating baby weeds. Produced by John Deere and created by the startup Blue River Technology, these robotic weeders look much like standard industrial sprayers at first glance, but each is rigged with an intricate system of 36 cameras and a mass of tiny hoses. They use computer vision to distinguish between crops and weeds and then deploy with sniper-like precision tiny jets of herbicide onto the weeds -- sparing the crop and ending the common practice of broadcast-spraying chemicals across billions of acres.
