These younger justices will likely be the face of the Supreme Court in the upcoming decades

The succession of Ketanji Brown Jackson, age 51, for Justice Stephen Breyer, 83, will add a shot of youthfulness to the Supreme Court and may present an opportunity for a reset at an institution whose reputation has slipped.

Five of the nine justices will be under 65, four of them of Generation X. They will be the face of the court in the upcoming decades.

For the immediate future, the addition of Jackson could prompt the court to reassess its response to diminishing public confidence. It has experienced a sharp drop in opinion polls. And the justices' lack of transparency on recent procedural and ethical issues has accelerated criticism.
