Because no level of intermediation is ever sufficient

Almost 30 robots have started teaching English to youngsters in a South Korean city, education officials said Tuesday….The 29 robots, about one metre (3.3 feet) high with a TV display panel for a face, wheeled around the classroom while speaking to the students, reading books to them and dancing to music by moving their head and arms. The robots, which display an avatar face of a Caucasian woman, are controlled remotely by teachers of English in the Philippines — who can see and hear the children via a remote control system. Cameras detect the Filipino teachers’ facial expressions and instantly reflect them on the avatar’s face, said Sagong Seong-Dae, a senior scientist at KIST. “Well-educated, experienced Filipino teachers are far cheaper than their counterparts elsewhere, including South Korea,” he told AFP.
