The statute of limitations exists to prevent unreasonable delay, to protect defendants from prejudice due to loss of evidence to the passage of time, and to recognize that people who are injured tend to complain immediately and not sit on their claims.

This case demonstrates why. Musk only complained after OpenAI was commercially successful with ChatGPT and after he started a competing effort. He repeatedly said “I do not know” and “I do not recall” on the stand, and argued that the passage of time made it hard for him to remember facts that would have been helpful for OpenAI.
