Real life has no scrub bar. You can’t drag back to the part you missed while staring at your phone.

Everything you watch has been made rewindable, and that has quietly changed what you expect of your own attention. You can miss a bit and drag it back, so missing carries no cost. Nothing outside the screen works that way: the sentence somebody says while you are looking down is gone, and no version of it exists anywhere.

The practical consequence is small and specific. When somebody starts talking, put the thing down first rather than halfway through. What you catch on the second attempt is never the same as what you missed.
