Re: What about...
"Yup, all we need is replace this stupid s##t with even stupider s##t like "30 cows in a field, 28 chickens how many didn't?" then wonder why the correct answer is "10"...:"
This went around my office a few weeks ago. I happened to be the only one who got it right. Doesn't bode well for puzzle-challenges.
Computers will eventually be better than humans at ANY of this, and inevitably the challenges will become unusable to humans but easily solved by machines. So what's left? Something involving body fluids? "Press the Auto-Pierce pad to collect a drop of blood and verify you are a human. We're sorry, your challenge failed, please re-sample and try again."
