I hate spam just the same as everyone else, so installing and using CAPTCHA fields is something I’ve had to get used to.

I have noticed that some CAPTCHA fields are getting more towards Mensa levels when it comes to solving them with upside down words and very blurred lettering.

I take it this means machine visual interpreting must be quite a bit more advanced now. I suppose it will eventually get to the stage where CAPTCHA fields are too difficult for human eyes to interpret, so computers will be needed to solve them!

A strange paradox!
