Captcha is not working consistently

After identifying/choosing the appropriate pictures/photos the verify button does not respond. The Captcha screen just sits there. It has been taking multiple attempts to be able to finally sign in.

Did you know that Google is behind Captcha and uses our responses to teach their AI how to recognize items in pictures? I've read several articles on it and it's pretty cool, but also a little scary that we may be helping to create SkyNet or Genisys (as it's called in the new movie).
