Indeed, Musk suggested that synthetic data — data generated by AI models themselves — is the path forward. “The only way to supplement [real-world data] is with synthetic data, where the AI creates [training data],” he said. “With synthetic data … [AI] will sort of grade itself and go through this process of self-learning.”

Elon Musk and other experts in the field of artificial intelligence believe that we have exhausted AI training data.

Tech tycoon Elon Musk says artificial intelligence will now have to write an essay or a thesis then grade itself, because the 'cumulative sum of human knowledge has been exhausted'

“We’ve now exhausted basically the cumulative sum of human knowledge …. in AI training,” Musk said during a live-streamed conversation with Stagwell chairman Mark Penn streamed on X late Wednesday. “That happened basically last year.”
