How tech giants cut corners to harvest data for AI

The artificial intelligence lab had exhausted every reservoir of reputable English-language text on the internet as it developed its latest AI system. It needed more data to train the next version of its technology -- lots more. So OpenAI researchers created a speech recognition tool called Whisper. It could transcribe the audio from YouTube videos, yielding new conversational text that would make an AI system smarter. Some OpenAI employees discussed how such a move might go against YouTube's rules, three people with knowledge of the conversations said. YouTube, which is owned by Google, prohibits use of its videos for applications that are "independent" of the video platform.
