Just when you think Jon Udell can’t get any more perceptive or articulate, it’s tomorrow and he’s written another column. (Really: he’s almost that consistent. The mind boggles, and the hands turn red from sustained applause.)

Today Udell analyzes one of the greatest security risks of all: the human-computer interface, where digits become sense data. Pull-quote of the day:

… we humans, with our legacy analog-only sensoriums, represent a terrible security risk.

Now as someone who still enjoys vinyl LPs alongside his SACDs and DVD-As and redbook CDs, and who listens to them all through a pressure-sensitive set of analog eardrums, I love my legacy sensorium. I’d love telepathy too, so long as I can post away messages from time to time and keep my mind to myself when I want. But Udell’s points are all extremely well-taken, and the writing, as usual, is as lucid and refreshing as a clear mountain stream.

That man’s writing teachers must have thought they’d died and gone to Heaven when he took their classes.
