That would save the AI companies money, but would not really get them more research done.
If the supply curve shifts right, quantity supplied increases.
As for whether it is much harder to enforce if there are automated AI researchers, I don’t know.
If we already have an autonomous AI researcher, there’s a good chance the researcher takes off to ASI while policy-makers are still trying to figure out what’s doing on. Originally I said it was harder to enforce but really I think the concern is that it makes AI development go a lot faster.
There is virtue in saying what should be done, even if it has minimal chance of actually happening.
