(VATICAN CITY) — Pope Francis on Friday warned tech company executives, diplomats and financiers that the race to create artificial intelligence and other forms of digital development pose the risk of increasing social inequality unless the work is accompanied by an ethical evaluation of the common good.

Francis addressed a Vatican conference that brought government envoys and Facebook and Google representatives together with philosophers, physicists and ethicists. A smattering of academics and Catholic bishops rounded out participants at “The Common Good in the Digital Age” conference.

The three-day gathering is the latest evidence of the Vatican wanting a place in the debate over the prospects and perils of artificial intelligence.
