But it s the time of year to take the long view. Indeed, I believe the first primitive versions of the next interface have already been delivered. They re called video games. The computer era of tomorrow will be created and controlled by the children of today.
Kids don t think of computer interaction in terms of menus and windows, but of games.
You could even say that the next interface is burnt into kids brains. A growing body of evidence suggests that early childhood patterns become hard-wired. Those that get used often survive and strengthen. The rest atrophy. You are describing an actual anatomical difference.
