    Constitution Breakdown #9: Alondra Nelson

    24/04/2026 | 1h 5 mins.
    This is the ninth episode of our ongoing series breaking down the U.S. Constitution.

    This month, Roman and Elizabeth discuss Article VI and VII, which include some odds and ends like the Debts Clause, the No Religious Test Clause, and the process for ratification. But tucked into Article VI is the all-important Supremacy Clause, which states that the Constitution is the “supreme Law of the Land,” and is probably the most frequently used constitutional law in practice.

    Roman and Elizabeth are also joined by Dr. Alondra Nelson, a leading expert on AI. She discusses why AI is a challenge to regulate, what to think of the tug of war between the states and the federal government on the topic, and whether she’s optimistic governments will figure this out.

    RoboUmp Hits the Big Leagues

    14/04/2026 | 31 mins.
    One study from 2018 found that Major League Baseball umpires blow about 14 calls every game. That’s 34,000 bad calls every year. And it makes a difference. A blown strike call can decide a win or a loss, a championship or six months at home, wondering what could have been. And while umpires are about 97% accurate in calling balls and strikes, Major League Baseball has been considering something drastic. Something to take us up to 100% accuracy. They have a plan to replace human umpires with robots. Now, with an update!
