Regarding "it would be impossible to train today's leading AI models": OpenAI has a pattern of equating humanity's progress with their own progress in their corporate communication.

A similar instance that bugs me is on the documentation page for their GPTBot scraper (https://platform.openai.com/docs/gptbot) where they say "Allowing GPTBot to access your site can help AI models become more accurate". Strange wording, given that is specifically OpenAI's models you're allowing, not "AI models" in general.

The goal is both cases is to make you feel like you're standing in the way of progress by objecting.
