Arguments in Favor of AI Fair Use

I made some notes on the nature of the training of LLMs, and about whether we as a society should consider the material used to train them as a fair use of that material. I believe it would be best for us to consider them fair use, and I made some points in its favor. The context of these points is US copyright law, which I did not spell out here.
