Odaily Planet Daily News: On December 22, local time, US President-elect Trump announced the nomination of Michael Kratsios as the next director of the White House Office of Science and Technology Policy (OSTP). Kratsios served as the White House Chief Technology Officer during Trump's first term and also served as the Under Secretary of Defense for Research and Engineering at the Pentagon. He graduated from Princeton University and is also a distinguished researcher at Stanford University. David Sacks, the AI ​​and crypto czar, commented on this on X: "This appointment is well deserved. Michael served in the first Trump administration for 4 years and knows OSTP inside out. We have spent countless hours discussing technology policy. Now, we will work together on these ideas under the leadership of President Trump. Very exciting!" Earlier, David Sacks posted on the X platform to deny reports of role changes: "Some traditional media reported tonight that my role has changed, which is completely wrong. I expect to spend half of my time in Washington guiding policy and the other half in Silicon Valley." Earlier, Fortune reported that insiders of the transition team revealed that the position was reduced from a leadership role to a general advisory position last week, partly because Sacks was unwilling 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 is still influential, often active in Florida and San Francisco, and meets with lawmakers. His appointment has sparked controversy over conflicts of interest, but some people in Silicon Valley are optimistic that it may help start-ups. However, others have doubts about his professionalism and are worried about the policy direction.
