I'm just gonna say it out loud...
These captcha, enter-the-text-in-the-image things are getting sooo
complicated, so difficult to decipher,
With the first casualties being those populations that are getting on
the internet but aren't very familiar with english letters...
That some day only machines will be able to decode them.
And that, will be the end of the internet as we've known it so far,
just because some people want to use bots to mine information, create
millions of fake accounts and bombard everyone with bogus ads.
