Descent to machines?

I have carried on many a long and wonderful conversation regarding man's path toward machinehood and have entertained numerous fears thereof. But, on a less abstract and philosophical note, those captchas!! Perhaps this experience is limited to only me, but I could swear that captchas are becoming more and more difficult to read these days. I sometimes find myself typing the incorrect captcha once, or even twice, before finally succeeding. I feel...diminished...less human. Are we becoming machines or are captchas just becoming too damn hard to read!? (All of you complained last time, so I decided to make it shorter. No, that's not what she said.)
