The suggestion of the OP if adopted would be another bullet shot into an important organ of SCOTUS. Soon, people would be put on SCOTUS as soon as they are 18 after a chip is put in their brains to control their reasoning.
At this point, I think destroying SCOTUS's credibility is essential for the wellbeing of the country. I would love it if Biden got the chance to fill a vacant SCOTUS seat with a 25-year-old recent graduate. The sooner the public loses all respect for it, the sooner it can be reformed. It's sad that it has to be this way, but oh well, it's not our fault.
