Software veteran’s public feud with Google escalates

A former Google engineer has managed to get under the tech giant’s skin, and the ensuing public spat is escalating fast. After receiving an unusually sharp rebuke from Google’s AI chief, the software veteran is now digging in his heels, refusing to back down from his controversial claims.

Steve Yegge, a seasoned software engineer who once worked at Google, ignited a firestorm last week when he asserted that a “buddy at Google who’s been a tech director there for about 20 years” essentially told him the company’s internal AI adoption was far behind the curve. According to Yegge’s April 13 post on X, Google’s internal AI adoption mirrors that of “John Deere, the tractor company.”

“Most of the industry has the same internal adoption curve: 20% agentic power users, 20% outright refusers, 60% still using Cursor or equivalent chat tool,” Yegge wrote. “It turns out Google has this curve too.”

Business Insider has not independently verified Yegge’s claims, which he presented as secondhand information. Google did not respond to a request for comment.

Externally, the narrative around Google entering 2026 has been largely positive. The company was seen as catching up to OpenAI in the generative AI race, erasing a once-embarrassing gap for the firm whose own research helped create the foundation for large language models.

But Yegge’s post sparked a wave of public backlash from Google employees, from top executives down to rank-and-file engineers. The most notable response came from Demis Hassabis, CEO of Google DeepMind, who didn’t hold back in his attempt to set the record straight.

“Maybe tell your buddy to do some actual work and to stop spreading absolute nonsense,” Hassabis wrote in a reply to Yegge’s original post. “This post is completely false and just pure clickbait.”

Yegge responded by saying he would apologize for his initial post “if Google can convince me that half their engineers are burning 4M tokens a day.”

A week after his initial claim, Yegge doubled down on Monday, writing that he had heard from “Googlers from multiple orgs” who described what he called a “two-tier system.” In this system, he argued, Hassabis’s team uses Anthropic’s Claude frequently, while the rest of Google largely does not.

“DeepMind engineers use Claude as a daily tool. Most of the rest of Google does not,” Yegge wrote. He added that non-DeepMind engineers “get pushed onto internal Gemini variants.”

“This is not a picture of an engineering org that is fine,” Yegge concluded.

Anthropic’s Claude Code is widely considered the industry standard for agentic AI coding tools. OpenAI and Google have rushed to catch up, but many software engineers still prefer Anthropic. Last week, Anthropic released Opus 4.7, which it described as “a notable improvement” and said users can now hand off their hardest coding work to the tool with confidence.

Yegge argues Google is cherry-picking rosy data to paint a misleading picture. AI adoption within companies is a major focus in Silicon Valley, with hyperscalers like Meta creating employee leaderboards to track AI token usage.

Addy Osmani, director of Google Cloud, responded to Yegge’s original claims, saying they didn’t “match the state of agentic coding at our company.” Osmani wrote that over 40,000 Google software engineers use agentic coding weekly.

“With so many friends working at other frontier labs and start-ups to give ourselves a baseline, Google is anything but average,” Osmani wrote.

But Yegge pushed back on Monday, arguing that Osmani’s statistic was misleading.

“Weekly use of a thin tool is precisely the box-checking I described in the original post. Volume of opens isn’t adoption , and ‘weekly’ is a low bar that includes a lot of people who tried it once and went back to writing code by hand,” Yegge wrote.

Overall, Yegge characterized the Googler backlash as spin. “You can choose to believe Google’s AI PR team and their core AI researchers, or you can believe your friends who actually work there,” he wrote. “I’ve made my choice.”
