If Trump is the top topic of conversation in Davos this year, artificial intelligence is a close second. There are literally dozens of panels on the topic scattered around this snow-buried village, as my colleague Adam Lashinsky reported yesterday. There seems to be no-one here who questions the notion that vast amounts of data combined with powerful machine-learning algorithms will not only transform almost every business, but also the way we live. But while the promise of AI is widely accepted, the practice remains fairly limited. Martin Reeves of BCG reported that his firm, working with MIT, surveyed more than 3,000 companies last year and found that while 85% of them believed AI would become a competitive advantage in the future, only a quarter were implementing it now, and only 5% were implementing it extensively.
