Google will now verify if you're a human by turning on your webcam and asking you to wave your hand
(docs.cloud.google.com)
This is a most excellent place for technology news and articles.
It says in the docs:
"## Accessibility
For users with accessibility needs who cannot use hand gestures to complete the challenge, reCAPTCHA continues to provide visual and audio challenges, and develop more accessible and secure alternatives."
So it seems you can just do a different task if you don't want to do the hand thing anyway.
Edit: obligatory F google still of course.
For now.
Also the last time I tried using the audio option on recaptcha it felt like a psychotic break.
