But who are "we"? The society, the government, the regulator, or the consumer?

I don't see any of such entity would solve that problem. The government and regulator are in OpenAI and Anthropic's pocket, and I don't trust them a single bit on coming up with regulations. The consumers don't care; they just need something smart and cheap. And the society doesn't work either: each person is too busy fighting for their own survival rather than changing the system.
