Silicon Valley investor David Sacks has become a significant figure in Donald Trump's administration, serving as chair of the Council of Advisors on Science and Technology and informally as an AI and crypto advisor. His influence is noted by tech leaders like OpenAI's Sam Altman and Salesforce's Marc Benioff, particularly regarding White House AI support for his investments. Sacks, a conservative with early ties to Peter Thiel, has dismissed critical reports as biased attacks, solidifying his role as a key technology advisor.
