Let's stipulate that relatively few people out there understand anything about how today's computers actually work. (I am one of the multitudes of non-understanders.)
And let's recognize that this is not a good thing. As we lose connection with how our tools work, we become alienated from them and from ourselves.
So it's great when, every once in a while, a piece comes along that helps explain a little about how these amazing machines work. This explanation by Weldon Dodd of recent advances in computer processors is such a piece. I don't follow everything he says, but it's clear enough for any neophyte to learn a lot about what's behind the latest advances. Dodd then explains how Apple is adapting to these advances.
