A Wider Aspect Ratio

A medical researcher shows two-year-olds widescreen videos to widen the aspect ratio of their mental viewing screens. It works by installing extra synapses. Kids become omnilingual and rule the world because their brains burn twice as hot as the average adult's. Their inventions include the telolfact and teletact, by which one smells or feels from afar. The Internet replaces transportation letting one experience any environment without risk to the body. Only products are shipped, which robots manufacture and lay rail lines to deliver them. The researcher's daughter grows physically and has her own at fifteen. By the time the granddaughter turns four, she takes over the stem-cell research to replace the genetic switches of narrow-aspect people. The reversal of roles isn't unprecedented, for as grownups discover, previous rewirings of man's brain also occurred when children used extra synapses to invent speech and writing. Their parents never learned because their synapses were dead.
