Bot or human? Creating an invisible Turing test for the internet

First off, I always thought the type of things described (tracking mouse movements, keypress jitter, etc) are already done by ReCacpha to decide when to present the user with a captcha. I am surprised they are not already doing this.

Second, I am surprised AI agents are this naive. I thought they would emulate human behavior better.

In fact, just based on this article, very little effort has been put into this race on either side.

So I wonder if is has to do with the fact that if companies like google reliably filtered out bot traffic, they would loose 90% of their AD revenue. This way they have plausible deniability.

They were very proud of this mouse movement stuff when the desktop was 70% of traffic.. It's not worth as much investment as its been given since there's no group limiting people to one HID method and removing accessibility from world.
