Google employees sign letter in protest of work for the Pentagon

WASHINGTON — Thousands of Google employees, including dozens of senior engineers, have signed a letter protesting the company’s involvement in a Pentagon program that uses artificial intelligence to interpret video imagery and could be used to improve the targeting of drone strikes.

The letter, which is circulating inside Google and has garnered more than 3,100 signatures, reflects a culture clash between Silicon Valley and the federal government that is likely to intensify as cutting-edge artificial intelligence is increasingly employed for military purposes.

Employees raised questions about Google’s involvement in Project Maven at a recent companywide meeting. At the time, Diane Greene, who leads Google’s cloud infrastructure business, defended the deal and sought to reassure concerned employees. A company spokesman said most of the signatures on the protest letter had been collected before the company had an opportunity to explain the situation.

Without referring directly to the letter to Pichai, Google said in a statement Tuesday that “any military use of machine learning naturally raises valid concerns.”

The company called such exchanges “hugely important and beneficial,” though several Google employees familiar with the letter would speak of it only on the condition of anonymity, saying they were concerned about retaliation.

The statement said the company’s part of Project Maven was “specifically scoped to be for non-offensive purposes,” though officials declined to make available the relevant contract language. The Defense Department said that because Google is a subcontractor on Project Maven to the prime contractor, ECS Federal, it could not provide either the amount or the language of Google’s contract. ECS Federal did not respond to inquiries.
