A pick-and-place robot running nonstop for a week logs 600GB — more than the 570GB of text behind GPT-3 on Song's slide — yet is nearly useless for a different robot or task. Song's rule: "There's no data size too small," as long as it's portable enough to aggregate. The graphic visualizes the stark comparison.
