A debate on the future of artificial intelligence (AI) in Europe drew a full house at the European Parliament - with MEPs and Commission leaders keen to find the best way to regulate and make the most of AI, while protecting us against its worst aspects, too. "We want to discuss this because you have to be cautious. Some artificial intelligence is simple, low risk, no risk, but some artificial intelligence may be life or death for you," says Margrethe Vestager, the Executive Vice-President of the European Commission. "So if it is very risky we have to be cautious, and all the rest of it, just go, go, go." And AI is already go, go, going fast, revolutionising areas like voice recognition and translation.
