It's totally fair to use GPL code, it just means all the models built by Anthropic, OpenAI, etc. using GPL-licensed source are themselves bound by the GPL. Plus, any works created downstream using those AI tools.

We're on the verge of a golden age of software as soon as someone finds a court with courage.

Ah, you have much more faith in the legal system than I do. It's nice to dream, though.

There's no difference. Either you need to follow the license or you don't. MIT has requirements still.

I think AI will create an open source dark age. Gradually, we'll see a lot less new good open source code. A gradual shift back to the proprietary world. Simmilar to the 1950-1990 period.

Why would giving more people software freedom and the ability to reverse engineer nonfree code result in a dark age?
