A discussion about captchas

I came across this website using a sweet captcha called “FriendlyCaptcha” - wow, what a relief not having to label cars and traffic lights split in the middle

It uses a JavaScript challenge solved by the browser. In a world where you can literally pay someone to solve captcha for you in a third-world country, is it really worth to use annoying captchas on your website instead of a JavaScript challenge or something similar?

Edit: This one looks interesting too, open-source, although not a JS challenge:

Edit 2: Friendly Captcha’s widget is open-source, the backend isn’t (edit: actually there’s a working script you can self-host, although it’s more like source-available than open-source in terms of freedom)
