The departure of Baidu Inc.’s most senior operational executive threatens to derail the Chinese search giant’s ambition of placing artificial intelligence at the heart of its business.

On Friday, the company stunned investors with the revelation that Microsoft Corp. veteran Qi Lu -- hired just over a year ago to accelerate its drive into everything from autonomous cars to digital assistants -- was stepping down because he could no longer work full-time in China for personal reasons.
