It seems like a great idea until the President randomly becomes a psychotic, Communist dictator, and Congress is full of Karens trying to make cutting in line a felony, meanwhile the Vice President is too busy getting black-out drunk to ever show up. That's hyperbolic, but you get the point.

Don't get me wrong, I literally proposed Supreme Court Justices be randomly selected, however, I also said the pool should be elected and appointed, because we can't have some random pedophile getting on the court and ruling that child molestation is now legal.

Sortition also makes politicians unaccountable. You'll see a trend of politicians doing something heavily disfavored of by their constituents the term before they're set to retire. Furthermore, there would be no mechanism for political change, just random people with no idea what they're doing, and not a single care in the world for what the People want. These are actually good things for judicial offices, though, since it makes them more impartial.
