Publicity stunt at Cannes or true disrupter of the ad agency model? We don’t know yet. But worldwide agency giant Publicis is skipping big conferences next year to invest in its proprietary AI system, which seems to be both a personal assistant and a replacement for Slack. A “conventional” agency that knows how to spell AI is rare, so Marcel is on the list primarily because it represents a much-needed step forward in what has become a rather stale industry. Don Draper would be impressed!
