Reels and Shorts derive their power from the fact that we pay higher attention to motion than to colors or shape. Blinking colors attract attention for the same reason. This observation makes it easy to neuter them: reduce framerate from 120 fps to 1 fps unless a touch is detected. This way scrolling will keep working as usual and videos can be watched if you keep pressing the screen, but the unwanted guests that abuse our attention will be left in the dust with 1 fps. Great for battery life too.
