Doesn't surprise me at all and seems like a good solution to the problem of human verification. It won't take long for AI to catch up to that, but this captcha method might hold for a couple of months.
Not sure what problem everybody here is having with this. The alternative would be device certificate stuff (ala did Apple sign for this being a proper Apple device?). Having to shake your hand sounds a lot more privacy friendly.
Are you guys seriously worried that Google is gonna steal your secret handshakes?
