Here's the problem: establishing that AI training requires a copyright license will not stop AI from being used to erode the wages and working conditions of creative workers. The companies suing over AI training are also notorious exploiters of creative workers, union-busters and wage-stealers.

Telling creative workers that they can solve their declining wages with more copyright is a denial that creative workers are workers at all. It treats us as entrepreneurial small businesses, LLCs with MFAs negotiating B2B with other companies. That's how we lose.
On the other hand, if we address the problems of AI and labor as workers, and insist on labor rights – like the Writers Guild did when it struck last summer – then we ally ourselves with every other worker whose wages and working conditions are being attacked with AI.
Our path to better working conditions lies through organizing and striking, not through helping our bosses sue other giant multinational corporations for the right to bleed us out.
