This bill if passed should only go into effect in 2024, at the start of a new Presidential Administration. Otherwise, Biden or Harris could name a new judge after 2222.

"A group of House Democrats introduced a bill on Tuesday to enact term limits for Supreme Court justices, arguing that the move will "restore legitimacy and independence to the nation's highest court."
The legislation, titled the Supreme Court Tenure Establishment and Retirement Modernization Act, would authorize the president to nominate Supreme Court justices every two years - in the first and third years after a presidential election. The justices who have been on the court the longest will be moved to senior status first."
