It kind of is, actually. Cloudflare, for example, uses a single CAPTCHA to prevent ongoing DDoS attacks. If they switched to this new reCAPTCHA and if a DDoSer can use Selenium to get past the challenge, then the CAPTCHA process has failed.
There are always tradeoffs with this. I strongly suspect Google is going to have to restrict it within a year or so, resulting in the number of users who still have to solve CAPTCHAs closer to 10-20%.

- rudolf0 12y agoThe work still has to be done manually in those cases, though, whether they type it themselves or rent use of a captcha farm.
- Dylan16807 12y agoIn most scenarios you only have to solve one captcha. Those are not going to be significantly affected, since the manual work is minimal. It will provide a multiplier on traffic in the case that a captcha is needed for every single action.
