It is just an old approach in new clothes. With this new captcha system Google still forgets the most important thing in stopping spambots. Human shouldn't proof that they are not a bot, but bots should proof that they qualify as a human.

I have reversed my approach on bot catching several months ago on my forums which have an average of 5000 spambot attacks per day. There was not one succeeding attempt in the last six months, even though no captchas or other human-intelligence checks were in place and all these forums allow posting without registration.

It shouldn't be difficult for Google to reverse their approach in the same way with only annoying the bots, rather than annoying the legitimate users.
