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

Note: The source confirms that Sam Altman attended Stanford University and dropped out to work on Loopt. However, the claim specifies he dropped out 'after sophomore year' (which would be 2 years), while the source only states he attended 'for two years' without explicitly confirming the specific year/class standing. The source does not specify the field of study as 'computer science,' only that he attended Stanford University. The core facts are confirmed, but one detail (computer science major) is unverified by the source.
