With Stack Overflow, GitHub and others, there is a mutual understanding that contributing can benefit the contributor. What is the incentive to continue contributing if the social agreement is, you get to help define a statistical weight for the next token and nobody will know?
I think the future business model may require AI companies to pay people to contribute, or it might not be a technology roadblock, but rather a data roadblock that prevents further advancement.
