The planned weeks-long protest was targeting Google’s involvement in Project Nimbus, a cloud computing and artificial intelligence deal between Google, Amazon and the Israeli government. More than 100 students took part in the demonstration, reports said, leaving their seats at Stanford Stadium while chanting “Free, free Palestine”. The students said the protest was intended to raise awareness of concerns surrounding the project and its links to the ongoing conflict in Gaza.Also read: ‘I lost my job to AI’: 24-year-old Meta data scientist says layoff was more relief than pain, big tech jobs are no longer safeStudents turn graduation ceremony into protest platformThe walkout came moments after Pichai began his speech, turning what was meant to be a celebration of academic achievement into a wider discussion about technology, politics and student activism.
