Hi, folks. I’m Jack Nicas, a reporter for The Times’s bureau in San Francisco, where two of us are rooting hard for the Red Sox, to the chagrin of our boss. (Those two are me and the editor who edited this, so we slipped it in.) I cover Apple, and this past week the news out of the world’s most valuable public company was not a new gizmo or doodad, but rather a withering critique of the technology industry from one of its most prominent members.

Timothy D. Cook, Apple’s chief executive, rebuked his Silicon Valley peers in a speech to European officials on Wednesday, criticizing them for building a “data industrial complex” in which our personal information “is being weaponized against us with military efficiency.”

As a result, he said, algorithms have magnified our worst tendencies and “rogue actors and even governments” have used our data against us “to deepen divisions, incite violence and even undermine our shared sense of what is true and what is false.”
