Pinball games were constrained by physical limitations, ultimately by the physical laws that govern the motion of a small metal ball. The video world knows no such bounds. Objects fly, spin, accelerate, change shape and color, disappear and reappear. Their behavior, like the behavior of anything created by a computer program, is limited only by the programmer's imagination. The objects in a video game are representations of objects. And a representation of a ball, unlike a real one, never need obey the laws of gravity unless its programmer wants it to.

Not every advance is progress. Not every new thing is better for us humanly.

Thumbs up or thumbs down on a website is not a conversation. The danger is you get into a habit of mind where politics means giving a thumbs up or thumbs down to a website. The world is a much more complex place.

There's a lot of research that indicates the brain rewards us for multi-tasking by giving us a shot of neurochemicals whenever we start a new task. Our brain rewards us even as our performance in every task degrades. We don't even notice that our performance is bad. We don't care. We feel like masters of the universe because our brain is chemically rewarding us for multi-tasking.
