Danish schools are asking students to orally defend their essays as a way of combating AI cheating. But the idea isn't new: it's a viva. And perhaps this old-fashioned emphasis on speaking, listening and debate points to something much bigger about education, work and the way AI is changing communication.

My clients are, without exception, intelligent and successful professionals, most of them working in English as their second or additional language, and doing really well.

Their 'communication skills' are excellent…

As long as it's written English.
