> saw this coming from miles away. Computers are better at solving CAPTCHAs than people are

good point... it's interesting how Captcha was initially popularized as a reverse Turing test, but it's just variants of Proof of Work today.

And it seemed clever at the time for Google to leverage this for improvement of their OCR models (it was!), and makes you wonder what utility is derived from the proven "work" today.

CAPTCHAs were designed as a type of Turing Test, not a reverse Turing Test. It’s not surprising that the effectiveness of these weaker variants has collapsed, given that AI can now pass the real Turing Test.

With the crosswalk, bike, motorcycle, stairs type of things, wasn't that just improving their training data?
