AI pets could replace dogs and cats, but expert warns that 'long-term effects' are unknown

A recent study found robots that speak in a "charismatic" tone while directing a college class can boost creativity among humans. Artificial intelligence could soon start replacing household pets -- no vet bills required. As various types of robots continue to hit the market, AI-powered "animals" have arrived on the scene as well. One example is Go1, the world's first intelligent quadruped robot "companion" that is developed by China's Unitree Robotics. The robotic sidekick walks on all fours, much like a dog -- but there's no need for a collar or a leash.
