Sam Altman — Education: Studied computer science at Stanford University for two years; dropped out in 2005

NoteThe source directly confirms all three components of the claim: (1) Sam Altman studied computer science at Stanford University, (2) he studied for two years, and (3) he dropped out in 2005. The source also confirms the additional context that he left Stanford to co-found Loopt. The Wikipedia article states: 'In 2005, after studying computer science for two years at Stanford University in Stanford, California, he dropped out without earning a bachelor's degree' and 'In 2005, at the age of 19, Altman co-founded Loopt.' All facts align perfectly with the claim.
