I am so torn on this. On the one hand, I think training these huge models is very similar to human artists consuming things and then consciously or unconsciously using it for their own work. The source is usually no longer distinguishable. So it should be allowed to train them on anything a human could consume.
On the other hand, large AI models are mostly under the control by huge asshole corporations and I absolutely hate seeing them benefit for free from the rest of us. It'd be nice if regulation like in Japan applies only for freely available models.
