Sure, for the bot. Captchas are pretty effective against bots, what's wrong with presenting the status quo to a bot? This is meant to improve things for the real people. I will appreciate not having to decipher some strange text.
I'm just not convinced from what's been shown that they'll have a long-term ability to distinguish between human mouse movements and those of a bot. So I'm curious as to really how one can keep this in place before it's overrun by spam and you need to make it more difficult anyway. More power to them if it works, but they're pretty light on details that inspire confidence, IMO.
There's no call for sarcasm. Do you have more insight into what data could allow them to distinguish between bots and people? If you do please share, because the Wired article and Google's own marketing video don't provide much information - it's obviously more focused on marketing than the technology.
