They are ridiculous, but they are so because what they are trying to achieve can no longer be easily achieved by solving the "visual acuity" problem.

Think of it as an opportunity to create something better. Personally I think shared secret with physical device has longer legs here but it does have a distribution/cost/re-authentication hump that is large. So far that has prevented its adoption but as you can see captcha systems are becoming non-functional.

I'd be curious to see the ability for a machine to solve picture based captcha systems. For example, given a lineup of 10 pictures of pets, choose the three that are cats. I've seen them before, just not widely implemented.

Well Google just talked about their code which identified kittens in Youtube videos. (http://www.nytimes.com/2012/06/26/technology/in-a-big-networ...)

I guess OCR software must be getting really good now!

With increased computing power, we are really able to do some amazing things. Unfortunately this also means that spammers also have access to this increased speed and ability to crack OCR based puzzles. But on the bright side, this also allows us to digitize books without humans more accurately (which is one of the primary purposes of reCAPTCHA)

And they are becoming less and less effective. Since they are so ubiquitous, users don't think twice about completing them. Therefore, infected users are going around unwittingly solving captchas served to them by their associated bot nets.

That's actually pretty interesting. With time the number of computers/processors required to do these tasks will go down, but for now and based on that experiment, it almost seems more efficient to use picture based captchas.
