Facebook chief marketing officer Gary Briggs is retiring after more than four years on the job, he posted on Facebook. Separately, Yann LeCun, an artificial intelligence pioneer Facebook hired in 2013 to run its A.I. research unit, will now be the company's chief A.I. scientist, according to Quartz.
Why it matters: Though Briggs will stick around to help Facebook hire his replacement, the move comes at a time when the company is facing growing questions about its influence.
