A child learns to talk in about 150M tokens, GPT-4 needs 15T tokens. Humanity needed the total speech of 110B people to evolve to current level, which comes about 51,395,437,500,000,000,000 tokens, about 3.4 million times more than GPT-4's training run, and 342M times more than a child needs to learn.

That is to show the relative cost between imitation and discovery. Evolution is on the order of 0.3 trillion times slower than catching up by imitation.
