The point of captcha isn't that you find boats on pictures. It's that you score high enough on some opaque metric.

That's why captchas come in different forms: math challenges, sound recognition, snooping on clicks, as well as captchas that will keep serving you challenges forever without ever accepting your answer.

If you can't hit the score, you won't be allowed in.
