According to news on December 21, Trump recently appointed David Sacks as the "AI and Crypto Czar" and leads the new advisory committee, which has attracted attention. Sacks is a venture capitalist, podcaster, and former PayPal executive. However, people within the transition team revealed that the position was reduced from a leadership role to a general advisory position last week, in part because Sacks did not want to leave the investment company Craft Ventures and did not want to go through the formal appointment process. In the future, Michael Kratsios will lead technology policy work, and Sacks will provide policy ideas. Despite the change in position, Sacks remains influential, traveling to Florida and San Francisco and meeting with lawmakers. His appointment has triggered conflicts of interest controversy, but some people in Silicon Valley are optimistic and believe that it may help start-ups. However, some people have doubts about his professionalism and are worried about the direction of policy.
