Ain't that the truth. Anybody remember jumpers on CD-ROM drives? Post-script? First personal computer I used had no memory; if you wanted to play a game on it, you first needed to program it. These days, I don't know anything about the internal workings of computers anymore. And I'm not interested, because I can do without the knowledge. I used to maintain that personal computers were introduced to consumers too early - everything was just too complicated. Not any more. So now I can focus on why I use them; I can focus on mastering the tools that I need to use. I guess that's not what Crabtree means at all, but his story is too vague for me. "A series of mutations"? What mutations? And why would they be inherently detrimental? One could suggest that the story shows that people are not getting dumber, but more attention-seeking. If it ever turns out that he's right, though, the solution is easy: put bone marrow back on the menu.
