David Sacks, a well-known entrepreneur and venture capitalist, has been appointed as the new AI and crypto czar by President-elect Donald Trump. Sacks, a close ally of Trump, has been a strong advocate for a pro-industry approach to AI and crypto, and has expressed support for a freer ecosystem that empowers AI companies to grow. He will oversee the development of AI and crypto policies in the White House, although the extent of his power and influence is unclear. As AI and crypto czar, Sacks will also be responsible for promoting open source and competition in AI, and has advocated for the integration of AI technology into warfare and national security tools. His appointment has been welcomed by leaders in both industries, but has also raised concerns about conflict of interest and lack of oversight. Sacks' significant financial exposure to Solana, a cryptocurrency, and his investments in other crypto companies have also been highlighted as potential conflicts of interest.
