Sir Michael Barber on getting ready for 21st century government

The last time I sat down to interview Sir Michael Barber, the world looked and felt a very different place. Even a few years ago, Donald Trump's tweets were making international headlines, Brexit had its supporters and detractors, and North Korea was an unpredictable rogue state harbouring nuclear ambitions. And just like today, governments the world over were striving to gain control over a fast-changing environment pock-marked by new technologies, diverse policy approaches and different ways to improve public impact. But of course, some changes are hard to miss. Artificial intelligence (AI), for example, is fast moving from concept to reality.
