The billionaire venture capitalist and Sun Microsystems co-founder lashed out on X at student protesters who walked out of Stanford’s 135th commencement ceremony while Google CEO Sundar Pichai was delivering the keynote address.

Khosla called their behavior “biased, idiotic, short-sighted and very selfish,” reserving particular contempt for what he described as “the stupidity of these Stanford students to take the greatest opportunity for equality in humanity ever… and go walk out on Google and Sundar Pichai that’s pioneered that.” The post quickly ricocheted across social media, drawing both fierce agreement and sharp pushback.

What happened at Stanford

The protest unfolded Sunday at Stanford’s commencement ceremony, attended by over 20,000 people, including nearly 3,600 graduating students. As Pichai — himself a Stanford alum — took the stage, between 100 and 200 students stood and exited the venue together, carrying Palestinian flags, blowing whistles, and chanting “Free Palestine.”

The walkout was organized by Students for Justice in Palestine and No Tech for Apartheid, who said in a statement: “We don’t need another tech billionaire to tell us how to get rich off of the killing and surveillance of Palestinians.”

The protesters’ core grievance was Project Nimbus — a $1.2 billion cloud and AI contract between Google, Amazon and the Israeli government — which activist groups argue could be used in ways that harm Palestinians.

Student groups also cited Google’s reported contracts with the U.S. Department of Homeland Security and Immigration and Customs Enforcement.

For his part, Pichai’s measured, apolitical speech focused on his personal journey from Chennai to Silicon Valley, urging graduates to “find a way to keep moving forward.” Despite the disruption, he continued speaking and declined to comment on the walkout when asked by reporters afterward.

Old guard vs. new activists

Khosla’s response was notable not just for its ferocity, but for the specific framing he deployed. “Selfish because they ignored the bottom 3 billion people on this planet that could benefit from AI and they are worried about their misinformed selfish self-interest,” he wrote on X.

In the Silicon Valley meritocracy’s lexicon, that reflects a long-held belief from Khosla that AI represents the most transformative equalizing force in human history, one that he himself predicted to Fortune could automate up to 80% of jobs by 2030 while also ultimately delivering broad economic abundance.

Critics of that worldview argue students have legitimate, substantive grievances. The walkouts follow similar Stanford commencement protests over the last several years tied to Israel’s war in Gaza, part of a sustained wave of campus activism that has repeatedly targeted tech companies over their government contracts and AI deployments.

A generational divide with real stakes

The clash maps onto a fundamental disagreement about how the tech industry should be held accountable — and by whom. Khosla’s generation built companies by moving fast and worrying about governance later.

The students protesting Pichai are inheriting a world where AI systems are already embedded in hiring, healthcare and national security decisions. Neither side is operating in bad faith, but they are speaking almost entirely different languages about what responsibility looks like.

Khosla’s Stanford connection adds an extra dimension. He studied there, built there, and has donated there. Watching students use that platform to walk out on the CEO of one of the world’s most consequential companies clearly struck him as a squandering of rare privilege. Stanford, in his vision, is where you build the future — not where you block the people building it.
