For 15 years, internet users have unknowingly contributed to Google's AI training through reCAPTCHA, a system initially designed to distinguish humans from bots. Originally developed by Luis von Ahn, reCAPTCHA evolved from distorted text challenges to image-based tasks, using human input to label data for Google's AI projects, including its autonomous driving company, Waymo. This covert data collection has been instrumental in training AI to recognize visual patterns, contributing to Waymo's $45 billion valuation. At its peak, reCAPTCHA engaged 200 million users daily, generating 500,000 hours of unpaid labor each day. This effort has been pivotal in developing Google Maps and Waymo, with users unknowingly labeling images from Google Street View. Despite the massive scale of this operation, users were never informed or compensated for their contributions, highlighting a significant ethical concern in AI data collection practices.
