> It would be great if there was some internal “make this benefit Main Street and knowledge workers” department, helping find ways for workers or creators to capture the value of some of the increased productivity.

If they wanted to do this, they could put their models in a public trust for the public's access and benefit in research, education, etc. Then it could be licensed, pay a dividend like a sovereign wealth fund, etc.

Considering that they copy and train on the sum total of all human creativity, a public trust is something that would be in line with both the spirit, and first and fourth considerations, of fair use doctrine:

    1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
    2. the nature of the copyrighted work;
    3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
    4. the effect of the use upon the potential market for or value of the copyrighted work.
